Thank you for the responses guys. I am also looking to be in the 10 - 12 grains per pound range as well. The Gold Tips get me in the range with 350 up front, but the Carbon Express would give me another 1.5 gpp over the Tips. I'm not quite sure I'm looking to shoot an arrow in the mid to high 600 grain range.
R H, yep she's a shooter. My Assenheimer shoots as good today as the day I got it from Donnie back in '95.
Ben, you got me thinking. If I dropped to 250 up front for the Carbon Express I would be right around that 10 gpp mark as well. Decisions, decisions.
