Widerack, I have taken many many deer with Slick Trick Standard profile heads. Yes they have a smaller radius BUT the angle of that cut actually blows a bigger hole. It's a steep profile which punches a nasty wound channel through a deer. I use them on my slower rigs as well as my traditional long re-curve bows. My higher speed bows I use the G5 Montechs. I DO intend to try out those Viper tricks in conjunction with my Traditional Long Re-Curve 60 pound bow. Them are some NASTY looking little devils. Might even give it a swing out of one of my BowTechs just for giggles.
