RE: broadhead's??
I'm sure you'll have good luck with the razorcaps as I've tested/hunted with em and they did an outstanding job. They're my personal favorite in fixed heads right now. The other posters are correct that the old 2 blade cut on contact will penetrate best but the razorcaps should be right up there or close to em. The reason I say should is because I've never conducted tests with that lowof poundage bow. I do know they work great out of my 63# switchback xt. I never realized you could get that much speed from that low poundage. I have to agree that when you go lighter to gain more speed,you lose kinetic energy and that means less penetration.
