Just got my bow back from shop after tune up, new string and cables. Went from shooting XX75's to carbon arrows. I noticed that there is alot more shock in the limbs now and the bow is far from quiet. Is that due to the weight change in the arrows? I also had the bow set at 71 lbs. Well I am not as tough as I thought and after 10 shots I was shot. I backed the limb bolts out 2 turns each which should give me 6-8 lbs reduction. It seems that the shock got even worse (or I might be paying more attention to it) Any thoughts would be appreciated. PS also went to a Whisker biscuit rest and it makes fast work of the vanes. After 3-4 shots the cock (white) is all wavy, but it is the only one on all 10 arrows, also it is starting to peel the vanes from the shaft.
