My bows run from 40# to 44# @ my 28" draw. At present I am shooting Grizzlystik Sitkas cut to 29" with about 200g up front between broadhead ( WW, Grizzly, Stos, or Simmons) and steel 75g adapters. I also shoot 2016s and/or 3555 GTs with a heavy brass insert added up front. All fly straight, and I've had pass-throughs on deer every time. The lightest of my bows, a 40# Shawnee, has carbon/foam limbs which I think have a bit more speed-- I get a lot better penetration with it (same arrow combos) than with a Bob Lee or Thunderchild, both 41# @ my draw.
