Hatchchaser- If you send those 350's to me, I will bare shaft them for ya out of my 67# widow. Of course at 29" they would be too short to send them back to you.
If I understood you corectly, you said they kick left in flight. I have been told that how the nock sits while arrow in the bag is the important thing.
I shoot those shafts and like them out of my 67#er but also had funny flight, but tuned straight in bag. (btw- I use 250g up front.
I shoot GT big game 100 out of my 82#er and the bare shaft flys true and straight out to 30 yards. Go figure. Anyway if you ever get the urge to come south and shoot some 3D. I have a 60 target range here in Albany,GA and your welcome to join me.
