Doo Sung Olympian Shafts

[Marcus]

Was given a Doo Sung Olympian shaft to have a play with (just one) on the weekend and these look like some very very nice arrows. They are a parrallel Aluminium Carbon shaft with a weight between the ACE and X10. The one I had was very very straight and the componants looked pretty good. Not ACE standard, but better than most.
From looking at them I would say they are a legit competition shaft and look better than the Carbon Techs due to the Alum/carbon makeup.
Best bot is they are around $30 a shaft made up!!
If i can get a full set I'll post how they shoot.

[Eberbachl]

Yeah, I haven't seen one of these shafts "in the flesh" yet, but I looked into them a bit when I was shopping for new arrows recently.

I think they look like a viable proposition for target, but the extra weight makes me think twice for field.

I'm looking forward to having a look at it.

:eek:confused:eek

[Marcus]

Well I still have the sample so I'll bring it Wednesday night. Am trying to get a complete set sent to me to try, Peter's looking into it.
Definitly a target shaft, however it would be worth doing some speed tests with them, I just bought Erika a set of X10's so we can compare the speeds of like sized ACE's, X10s and Doo Sungs and see how they go. I did lose about 4 colours worth at 30m with them though. :(

i've just ordr a ste of 12 of these (i only saw your post after is, i was hoping when i saw the subject, that is was a good comment ) :)

[Marcus]

What size for what gear?

These are really awesome shafts. If you have access to a laithe though it's worth turning some ACE pin down and using pin nocks with them, really nice with those.
Super straight and some really good scores being shot with them at our club. One of the recurve guys is shooting PB's weekly with them and some of the compounders are shooting perfects at 70m and 58's at 90m with them. Top shaft at a great price. My ACE's are flying so poorly right now I'm looking at moving to them full time.

[Pat Mole]

28" shafts for 38 pound limbs, and getting a new hoyt elan handle, should arrive at the same time as the arrows

[Marcus]

Ohhh very nice choice of riser there Pat. Let me know how they go for you, both the arrows and the riser.
BTW my wife's limbs are 38# Carbon plus limbs. I don't think she will sell sperate to the riser as she has another riser and is thinking of going back to recurve in a year or 2.

[Pat Mole]

ok, thanx anyway

[Marcus]

She wants about $300 for them if you are interested.
$850 if you wanted the Avalon riser with the limbs.

[Kuru]

Marcus these carbon plus limbs your wife has got, they wouldn't have a problem fitting into an axis would they ? Let me know if their still up for grabs as I may be very interested in picking them up

[Marcus]

No they will fit in an Axis. If Pat doesn't want them (as he asked first) then get your people to talk to my people and we'll make a deal.

Luke, could you please explain why a heavier arrow isn't good for field but is alright for target?

I've always wondered what makes an arrow a field arrow as opposed to a target arrow. :confused

[Pat Mole]

if gareth watns them, i got no prob, it will be a while before a can afford anything :(

Hi Foo,

Because I shoot alot of unmarked field (ABA and 3D) as well as marked target shooting I need to consider quite a few things when I select my arrows.

In marked target events, the main thing with arrows is that they should all be straight etc , all the same weight etc... of course ( the same goes for field arrows), but a couple of things make them particularly good for target.

An arrow with a very thin diameter can be important on the target range, especially when shooting longer distances, as the smaller diameter will attract less wind drag. The other thing which can help a target arrow is a little extra weight. This has the effect of stabilizing the arrow in the wind and resisting the effects of the wind because of the weight.

On the field course, wind is generally not so much of an issue because 1. we are usually shooting shorter distances, and 2. the field course is often sheltered from the wind. Although I do like a thin arrow on the field course, it is not as important as on the target range. The big thing about arrows for unmarked field is that they need to be light. Where a good target arrow can be heavy to resist wind, when we are shooting umarked distances we need to estimate the distance, and if we make a mistake about that estimation, even by a couple of meters, the arrow can drop out of the target.

Because an arrow's trajectory is that of an arc, a heavier arrow will drop further out of the target than a light arrow. To illustrate this point, imagine this: I am shooting a field course and have two different arrows. One is my trusty Easton ACE (which is thin and very light), the other arrow is an Easton X10 (which is thinner and a bit heavier). These are both first class arrows. I am standing in front of a target which is really 50 meters away from me, but I think it is only 46 meters away. I set my sight and shoot each of the arrows. The ACE because it is light has only dropped into the 4 (on a target which scores 5,4,3,2,1)...but my X10 has dropped all the way into the 2 because of it's extra weight.

So you see, we must make compromises! If I shot target only I would most likely be shooting X10's, but because my distance judgjement is not that good, I prefer to shoot ACE's which are a better unmarked field arrow. This, to some extent is obviously at the cost of some wind drift when I am at the target range.

Regarding the Doo Sung Olympian shafts, they do look quite good, but because they are a bit heavier than my ACE's I personally would only cnsider them for target.

Anyway, I hope that rambling made some sense! It's late (that's my excuse :D)

Cheers,

Luke.

Bows Arrows Bits Store shooter Paul Malynn from Queensland shot a 1397 Men's Fita with his Doo Sung Olympians in practise yesterday. These shafts are really looking the goods.

[2Dogs]

I got 2 sets of these arrows that I've been shooting for a while. 500's & 400's.

I've been fairly inconsistent with the 500's but have had a lot of success with the 400's in getting them tuned for my Hoyt.

So we shot a Fita at the CLub yesterday, and i shot a PB of 1397. I'm stoked :eek . Ranges were 337,348,354,358.

These arrows are impressive. I've got ACE's X10's McKinneys & Olympians and I'm going to keep shooting the Olympians.

The 400's weight in at 337 gr with EP175 vains, 100 grain points and with ACE pins & nocks. 276 fps out of my bow. Would recommend the ace pins & nocks.

For my grouping, wind drift I would compare them with my X10's. I really don't see any value in buying a set of X10's when you can get 24 Olympians for the same price.

For any you guys considering a new set of target arrows, don't be fooled by the "cheap knockoff" image that some of the cartel products have got. These arrows are bloody good.

I'm ordering another 12 tomorrow.....and no I don't get them for free

[Bruce]

I am also completely satisfied with my doo sung arrows . Mine are quite heavy as I wanted them mainly for field and some target. I use the 400 size with the full 110 gn point . They way arround the 360 mark but I don't mind I only want them for marked rounds . I am still getting over 285 fps with them but best of all no wind drift or if there is very minimal

[Pat Mole]

well, i got myn just last thursday, and any new equiptment is great to me :P

[Kuru]

Anyone know what they're like coming out of a recurve ? As I'm thinking about maybe getting a set but can't justify X10's for the recurve and compound. Also how much is the variables in weight on average ?

[Marcus]

The Doo Sungs are made by the Koreans. The Koreans are the best recurve shooters in the world. Cartel is a top maker there...need I go on? One of our recuve shooters is using them and loves em.
As for weight, I posted about that somewhere else where over the 12 arrows theer is 0.5 grain difference and 8 were under.1 of a grain. This is without filing etc. Overall I would say on average the weight variance is about 0.2 grains which will make SFA difference at 90m with a compound.

Trust me when I saw these arrows are awesome for the price.

[Kuru]

Cool thanks for that Marcus. WIll give them a try with the recurve. Gotta decide which bow I'll shoot full time, just to expensive shooting both !!!

[Looking_4_X's]

Paul Malynn, did you get the ACE pins machined down? if not where did you get them, i've been looking to put pins in some i've got but haven't had any luck.

[2Dogs]

Yes I got the ACE Pins machined.

Bows Arrows & Bits ( http:\\bowsarrowsbits.com ) in Werribee sell the pins already machined down. That's where I got mine.

Any decent machine shop could turn them down.

Cheers

[mike]

So, how much are the DooSungs per shaft at say bows arrows and bits? Do they sell in sets of 12 (pre-matched of course) or are they sold individually?

I will need to get a set of target arrows after the indoor and these look pretty good.

[GaryH]

And how much are they charging for the machined down ACE pins???? Anyone have a spine (frequency oscillation) :roll: chart for these little gems???

[Marcus]

I think they are charging $30 for a pack of 12 (give or take a few $). About the same as the X10 pin nocks. The high price is due to the cost of buying the pins in the first place. They tend to last a fair while so it's worth the $$$

[GaryH]

Thanks Marcus, I'll have to give them a call.
Still need to find a spine chart or at least a comparison with something from Easton.
Currently shooting Recurve 40# @ 30", any ideas??

[Marcus]

Should be similar to the first number from the ACE chart. So if you shoot a 520 ACE go the 500's. If you shoot a 620 ACE go the 600's. I'll find the real spine chart and look. Otherwise call Bows Arrows Bits and talk to Peter or Steve and they can look it up for you.

[Kuru]

Gary, There is a doo sung arrow chart on the alt services site
