Noticed my arrows flying a little stiff. Have to back the plunger tension back to get them to move to center. Problem is I have to back out my weakest spring all the way out and am barely getting to center. I am shooting 36lbs, 600 goldtip entradas with 100 and tried 125grain tips. My cheetahs fly a bit more to center at 650 spine and 100 grain tip. Just curious as to what you guys shooting the lighter weights are shooting and what grain tips they are getting good tunable flight with. Just need to move em about 2 inches more to the right out at 40yds. Will probably just increase my draw weight a full turn or 2 and see if that helps.
