Hello all. I was shooting PSE STL Hunter 300 Radial X Weave arrows with 4" Quick Spins and 100gr Thunderheads with EZE-Crest on a PSE Carrera at 65# at 85% letoff and a NAP Quick Tune with no problems at all. I switched to Gold Tip XT Hunter 5575 using the same setup EXCEPT 2.25" Quick Spins. Nothing else has changed. The problem I am having is my new arrows are corkscrewing and hitting at odd angles at 20 yards. I have checked my straightness and that is fine and the B/H's seem to be spinning right. What am I missing? Why are my arrows flying so far off? When I shoot them with field tips, my impact points are very different. For the most part, I am still hitting groups with arrows stacked ontop of each other. They open a bit with the B/H's.
