I hunt primarily with a recurve, but have been working with my Mathews Heli-m on paper tune and arrow flight. I keep having a problem with my arrows fishtailing in flight. I've paper tuned and I'm getting a decent hole, but I had to move my rest (QAD) quite a ways to the right so that my arrow is way right of center when looking at the bow from above. I've had this issue in the past and thought I had it corrected. I replaced the grip with a Shrewd last year. I'm shooting CX Maxima red 350's and about 63#@28" so I don't think it's a spine issue. When I move the arrow to the center of the bow my arrow flight is really bad. Any thoughts?
