I have been shooting AD trads cut at 29.5" out of a 60lb lb that is cut past center. Bareshafting shows very weak at 15yds, (2 ft left, nock rt). I keep adjusting the sideplate out, shaft still shows weak. Take side plate off and get weak! So I shoot paper with a full length fletched shaft and still get weak, start cutting a 1/2" off at a time until I get to 29", still weak!!! I can only assume since these shaft spine @ 85lbs that they are actually so STIFF that I'm getting a false weak and the arrow is bouncing off the shelf? all setups used a 100 grain insert and 125 grain point (I have played with point weight as well). While shooting paper I try another set of arrows and get a perfect tear (feel I have a very good release). Really like the AD's and hear so much positive about them and how tolerant they are, just want them tuned as best as possible to the bow.
Sure appreciate any help!
