I’ve been shooting all summer with some 30 year old Easton “Autumn Orange, XX75, 2117” Shafts, fletched parabolic, and getting great arrow flight. I’ve just switched to my hunting shafts, “Easton Legacy, XX75, 2117” shafts, fletched shield style and getting crappy arrow flight. Both sets of shafts are cut identical length with identical weight. I’m pretty sure I’m not getting any feather slap. Could it be that the shafting has changed over the last 30 years? Are the new Easton shafts different in composition than the old ones?
