Atlasman

I switched from GT 5595 to GT 7595 with feathers, now my arrows are spined correctly for my setup, FOC is at 10.5%. I paper tuned and I am getting bulletholes. Grouping at 30 yards is excellent. My only grip is that the arrows are corkscrewing. It is really noticeable from 30 yards+. When your arrows were corkscrewing which adjustment did you make first to the WB. I have the deluxe so I can adjust either way. I like the groups but like you I want excellent arrow flight.
