60 pounds will be plenty, especially if you are going to be getting a 2006 BowTech. Check this out...You can put the speed cams on the 60 pound bow, have it cranked all the way upand as compared to other brand bows it will perform like a 65 pounder. That set-up fills a perfect void for those who are stuck deciding between both 60 and 70 pounds. Plus if you want that very same bow to feel like a 50 pound bow, you can dial it all the way down and install the smooth mods on cams. Couldn't ask for more than that. Good luck!
