I also was not sure what broadhead to shoot , I had some shockwaves 100 gr, i bought some montec' s 100gr and shot them from the same bow , the same shafts, and into the same target. the shockwaves went right at 75% through, then i took of the shockwave and installed the montec and shot at the same target, in a new place so not to use the same hole, the montec went through the target 100% and put the shaft 5 inches into my backstop, my own test made my mind up on this question . thanks for letting me put in my 2 cents .
