bruce,

I agree with you. I should have stated a minimum DW when making my post. Lower DW's would benefit from the increased FOC.

I'd like to thank whoever told me about the Arrow Dynamics Nitro Stingers. I purchased the "Gold" model which is 8.9 gpi and my total arrow is 437 gr. They are an easy$85 way of increasing the FOC with standard BH's. My FOC went from 12.3 or so to 14.5% just by switching to these arrows and no change in arrow weight from the GT XT Hunters.
