Young Deer Hunter, I played a bit on Archer's Advantage (a software program that helps determine arrow spine, weight, speed, etc.). I'm getting about 46.5-47lb of kinetic energy for your setup with a 350 grain arrow. Of course, this is just an educated guess. But, I've found AA to be pretty accurate.
Assuming your going after whitetail, I see no problem in you using a smaller mechanical like the Innerloc EXP 2 blade, Rocky Mt. Snyper, or Rocket Steelhead. Fixed blade, any quality head will do. Everyone has their favorites.
