Martin Ridge Hunter,75 lb draw weight with 27" draw length. I forget the exact length and spine of the carbon arrows I'm using, but they're fairly long. The heads are 100grs. and this being a single cam bow, I'm only getting around 255 fps. Short draw lengths suck for generating high speeds, but I shot a lot of deer starting in the '80's with a bow that didn't quite break 200 fps, so I don't worry too much about speed.
