Got a Silvertip that still makes a thomb noise. Literally that is what it sounds like. It is not twang or slap, it is thomb. It bothers me but not deer, i was wondering if since i am shooting 3 under is making the tiller out of wack. I bought it off tradgang and did not even ask if it was tillered for split or 3 under. It doesnt matter because i shoot it great. Just wondering if i could double up on some puffs on one of the limbs to equal the tiller out. I have bow hush on string and puffs also. If anyone has any insight it would be appreciated.
