Man you ask a lot of questions...but heres my input. I have personally used GoldTip xt hunters and CE maxima 250s. I have seen a GT shot into a huge oak tree, and be OK to shoot again. I wouldnt suggest doing this on purpose b/c of seeing carbon arrows explode like i have seen pics of on here. My maximas are pretty strong too, but way too expensive to be testing there limits. I have missed and hit rocks with these arrows and had them be fine, then again i had one arrow that hit a rock and cracked. I think every arrow is going to have it's limits. Some ar going to e OK to shoot again and some are gonna be trash after that kind of impact.
