Well, got the slick tricks in the mail today and couldn't seem to get them to group with my field tips. At 30 yds, they were left of the field tips by about 4". Moved up to 20, still about 4" left and about 3" low... I thought it must be a tuning issue, so I bare shaft tuned at 20yds. Bare shafts hit approx. 2" high and 6-7" left. Now I'm thinking its a stiff spine, my question is even with a short draw at 71# could it be that my ideal arrow would be a 3555 []
