I have 6 of the sitkas and 6 alaskans, I had trouble tuning them, Initially cause I was losing inserts into the targets. You should only cut them from the front But you have to do it in Steps, so you have to partially glue the inserts in, Shoot, remove insert and cut, then re-glue, Quite the process, I like to Bare Shaft too I had a hard time with this as well, SO I lightly Fletched (3 x 3") to get some stability that helped a lot, But after all was said and done and the cutting process, the arrows turned out lighter than I had hoped,
Back to square 1, I am really giving them a fair shot, But for their cost seems hardly worth it..
They Are however the Pretiest shaft by far out there..
