    OK, I looked long enough. Now it's time to talk. About the only thing I can think of is that the cams are over rotated. They may be in time OK, but just too much rotation. I have never seen a pic or anything showing where optimum cam position is. I had this very same problem with my 2006 P3. I twisted the string down to remove some of the cam rotation and got the draw length back by relocating the module.

    I'm sorry I can't add more. Maybe if you post this on www.archertytalk.com you'll get some more responses.

    Limb savers can never hurt. Hold on, you got it backwards. You put twists in the string to shorten the draw. Without seeing the bow I wouldn't have any trouble putting at least ten twists in the string. And I'm not saying this is the problem, but it might be.

    Couple other things. Take measurements of things before you start. Remember what you did so you can undo if it doesn't work. Twisting the string will reduce the draw weight. Be aware of it.

    There may be certain tradeoffs here. And if things really get screwed up just forget my name, please. LOL.
