I can only say that I think they would be. I shoot a 55-75 hunter arrow with a 125 grain head this past season out of a 74lb. 50% let off bow. They did quite well, stiffer than beaman 340's. If wieght is what your after maybe you should try a diiferent make. I believe gold tips are lighter than others. Only one way to find out if someone else hasn't already, shoot one through some paper. Been wondering about these myself.
