Just made a 'boo cored flat laid, osage belly strip long bow It is 50# @ 28'' and have been trying to perfect the tiller on it for 3m under. I have traced the upper limb at full 28'' extension and flipped the bow and compared profiles and have them identical. Using split fingers it is virtually noiseless, but with 3 under, even changing brace heights, and nocking point I still get a little 'twang' on the shot.Tiller measurements at the fades are about i/16'' positive on the upper now , but have tried various tillers from bottom positive to upper positive to neutral and can get it virtually silent with split but not 3 under. What say you?
