Just picked up 6 of the short 3 fletch arrows to try out over my original longer fletching. My older arrows flew straight and could keep groups in the 3" area at 35 yards. With these new ones I am all over the place, haven't noticed fish tailing, just can't get a group. I shoot 6 of the older arrows a back to a nice group. The arrows are cut to the same length and for the same poundage I am shooting, both are just standard straight 3 fletch. I'm shooting a PSE set at 65 pounds with a wisker biscuit rest. Maybe just overlooking something but it's getting frustrating. Any input please! Thanks
