The GT 75-95 is a very stiff arrow. One cam bows like stiff arrows, but they are not as necessary on two cam bows. Besides, the consistentspine of a that arrow is questionable. With the tear the way you describe, it indicates a possible over-spined condition.
I've tuned quite a few 31" Guardians and just one on Friday -Trestand's. They all tuned just fine. Trestand is very happy with his. He just posted on Davidmil's thread.
Thx Len that make sense. Will try again with a different arrow. I have Pro 40, Hoyt UltraTec, Ross and a Mathews and all shoot great. This one just confused me.
