I was wonderingly what the brace heigh should be for my 64" diamonds series I had to get a new bow yesterday because my other cracked I am having a really hard time tuning it its 57 pounds just like my other I'm shooting 7 1/2 brace height with the same arrows but it still continues to porpoise. Also it seems like they changed the grip on them any thoughts
My Tomahawk is 60@28" I pull it to 29".I was able to set the brace height at 7 1/8 it worked great I also use a heave arrow around 617 grains.
Porpoise is usually nock height. The tiller may be slightly diff on the new bow or the grip may put more tension on one limb than the other bow, so you might have to play with the nock setting on string.
I have Tomahawk 64" 50#28, brace height is 7 3/8"
what Kenny said...brae height. I kept my ss at about 7.5"
