I have some GT 100+ that someone cut down to about 30 inches, I don't think I'm going to need those, there too short. I have some others I was shooting off of a 73lb Chastain/BearTakedown that are about 30 and a half. There bending ok with a bunch up front, 450 I think. I haven't shot it too much though. LOL. But I think one could make some really gnarly arrows with these by putting them inside what ever alunimum would fit on them.
