I just purchased another bowtech constitution. This things is night and day better than the other one that I had. Anyhow, after about 150 shots the nock point moved about 1/4" low. So I moved it up and everything is fine. Except I'm only getting 65% let off at the 80% setting. Any Ideas? The bow is obviously out of "time".How much can you change the string specs before it locks out?

How are your two bows different? You can put a few twists IN your cable going to the top, outermost post on your top cam. This will put it "behind" the lower cam and give you more let off and valley.

Thanks Walks. I got to thinking last night, and once I put the top cam behind the bottom the let off cam in perfect. The first constitution was a work of art. It had terrible vibration, noise, and was just flat out inaccurate. With this bow I might just become a believer in bowtech. I'm impressed.

Hmm, I'll bet your first one had the wrong length string and cables and the cam positions were not proper..
