RE: IBO speeds @ less than 70lbs for Bowtech Pro40???
My 04 Pro 40 Dually out of the box was shooting 326 at 30" 60# with a 301gr 3D select shaft. I shortend the draw length to 29" at 53# with a CE CXL that weighs 315 grain it is doing 285f/s. I will bring the weight up to 60 by summer. Fantastic bow the best Bowtech I have owned yet. can't wait for my Extreme VFT to show up.
