My 6 year old High Country Ultra Force with Hatchet Cams is 65%. I like it too much to upgrade to anything else. Very quiet for a two cam. With the 60lb limb cranked down and measured at 61 lbs. I am getting 250 fps with my old 501 grain arrows, and 274 fps with my new 375grain carbon arrows. The set-up is very efficient. I've had the cables and string replaced once. Unless something happens to it, I have not plans on getting a different bow of any letoff.
