im shooting a 58inch shrew samurai, i draw 29.5 and i know the recomended brace height is 7 to 7.5 but when tuning i get great flight anywhere in there but alot of noise, when i creep up to 8 inches even she goes silent and arow flight and acuracy is still the same. I used to measure my brace height to the highest point of my shelf where the arow rests. and i used to think i had a bh of 7 5/8 but when i realized it was mesured to the deepest part of the riser it was up to 8. I was kinda wondering if a whole half inch above the recomended could hurt anything.
this is a new issue i draw 61 and used to shoot 600 gr arows and never had a noise problem, now i shoot 820 gr, and am happy with the results just not the noise. anyone else had this happen?
sounds strange
what string are you using?
Are the heavier arrows a stiffer spine? They could be smacking the riser.
9 strand d97
i used to shoot gt 5575 but now 7595 I spent a good bit of time bare shafting and they fly well.
A higher brace height will not hurt the bow but you are robbing the bow of some performance. All Shrew bows come from Ron and Gregg with a 450+ string. I would as Ron has to me in the past going back to the 450+ string and see what happens. My guess is she should quiet right down for you. I have a 58" Samurai as well and it is by far the quietest Shrew I have.
i had two 450 strings one broke due to a broken nock the other began to break so i swore them off, I just like the bow to much to risk doing that to it twice.

JR,
I too am wondering if you have a spine issue? I shoot my Samurai at 7" to deepest part of throat on grip. I'm drawing 29" and use Easton Axis 400's with 200 grain points (standard aluminum insert) and 4 inch parabolic low cut feathers. Total weight is about 560 grains and I'm drawing about 59#. I use a six strand string from Ron and have had it on the bow for years. I use two rubber cat whiskers for silencers and that's it. Extremely quiet bow. I know if my nock point or spine is off, the bow will be noisier.
