Sight extensions/torque & brace height

[Patchy]

Would it be a fair assumption that the ideal place for the extension would be determined by brace height (that is where from the arrow leaves the string) for example If i were to install a STS the arrow would leave the string at the bows Measured brace height say 7".
Then wouldnt the ideal length of the sight bar out be 7" ???

If you install an STS, I have a bridge for sale. Lets talk.

[Patchy]

what are you talking about ?

[New Tricks]

Big bridge. Look like a coat hanger. Number 1 friend price. We got a deal? Or I could sell you an STS. Either way you will be untra happy AOK fan of me.

logic says it doesn't seem to be the case. But logic isn't always correct.

[Patchy]

Ok not to many replys so wouldnt this be the case though?

possibly another reason why a few pros are shooting with sight extensions in?

[Quackor]

Is there any science backing your theory? Or some kind of gut feeling?

[Patchy]

These are my thoughts

if those are your thoughts, then why are you asking us? it's obvious from the diagram that the ideal spot is so that the sight extension is equal to the brace height.

however, i wonder what disadvantages (eg. long term effects) there would be by having the majority of torque concentrated in a particular spot that is brought by having the sight extension equal to the brace height? i would have thought that having the torque diffuse throughout the bow is better than having it concentrated within a certain spot.

From instinct, I would say that brace height has an effect on the optimal distance to have the sight extension, but I don't believe that it is as empirical as you propose. I would suggest that it depends a lot on the dynamics of the bow - poundage, speed etc, rather than just the static geometry.

That diagram looks yummy. Burger button.

It aint related to brace height, I know of bows tat have their optima position 10" out from the bow, but have a BH of 7.5"
Also riser design is a huge factor.
