Been shooting them for 2 months allready so far great, preety tough arrow
havent hit any game with them yet since our seasons ended about 2 months ago,and hiting the tree did not really test its strenght.
no difference in performance from the maximas ,but they are suppose to be tougher i think they weight just a hair higher then the maximas too.

i dont know but i cant say nothing bad about them except maybe the price
