If you have access to achonograph you can play with all kind of things. I know on my 2001 Ultratech I have the versa cam, and I played for hours on that thing. Adjusting the let off and drawlength, I finally got a setting that gave me an extra 8 fps. I do not know how this is possible but the cronograph was consistent when I made changes. The versa cam is a little goofy in that if you adjust the let off pin it actually adjusts the drawlengh slightly by adjusting at what point in the draw cycle the stem from the cam hits the string.

You can also play witht the speed nocks on the string, different arrow nocks. I wish I had a chronograph I miss playing with my set up.

How heavy are your arrows that you currently shoot?


Good Luck
