Jeff I completely understand your thinking and (I hope heis not watching this[8D]) but the longer I do this the more I agree with AurturP that momentum is more important than KE. I shoot kind of a mid wieght setup. I am shooting a 434 grain arrow at 287 fps. I have always gotten great pentration out of this setup. According to Dr. Ashby's study of momentum (depending on the braodhead coefficient used) I am getting close to the magic number of .57 foot pounds of momentum. I shoot mechanicals either Undertakers or Rages depending on the day. I have had great success with both. I actually shot a doe the other day and dead centered the femur on the offside leg as it exited and it snapped the leg bone and still passed through. I shoot a heavier arrow to slow my bow down and would actually prefer another 25 grains of arrow wieght (125 grain head) but they don't make a 125 grain Rage or Undertaker so I switched back to 100 grain heads. I think you will definitely see your pass through percentage go up though I am suprised you are getting them now. Good luck! Let us know how it turns out.
