Not only will you get better down range performance from a heavier arrow, you'll also get a much quieter bow to shoot. You're a big boy, give up a few fps, add about 100 grains to your arrow weight and you have really got something with that 29 inch draw. I might even try to beef the poundage 2 or 3 pounds to help hold some speed. You want to be a speed freak on the range...fine, but for hunting and shooting broadheads I'd go the other way.
