Another line of bows that are screaming fast are the Martin's with the Nitrous cams. I'm shooting a 3D setup, but at 27.5" draw and 55lbs it's getting 290+fps. At 58lbs it does 304fps. Not bad considering that the bow draws a lot easier than the Bowtech. Try a look at the Martin SlayR or Cougar Mag with Nitrous cams.
