what bow are you shooting and Draw length/limb combo?I like to keep my hunting set up shooting 280-290 FPS. I shoot as heavy an arrow as I can get away with and keep it in that FPS range. 510ish grains (give or take a few) is around where I am at now. No idea about the FOC, but its heavy/fast enough for about any situation I could be in without sacrificing to much trajectory.
My 2 cents....
I am in the same camp as you that I like a combination of both but I think folks will have a hard time getting those numbers on most bows. My Nitrum turbo is barely doing that with a 29.5" draw and draw weight at 74lbs.
