The specs aren't right on your bow. If you look at the 2008 catalog (on-line) you'll find the Mystic on page 18. If the bow has a sticker on the bottom limb the first two #'s of the erial number indicate the year of manufacture.
The a2a of the bow should be 40" and the brace height should be 7 1/4".
Tis is just an educated guess at this point but I'll bet the string is either twisted uo or just short by maybe 1/2". This would account for all the symptoms you are encountering.
As for the one cable hitting before the other it might be that the cables need tweaked. You don't adjust the stops, as you are calling them. I think you're referring to the cam modules. They are used to set draw length. However, it's possibly that if one cable is slightly longer than the other the cables might not hit the flat part of the module at the same time. If this is the case then you should be able to see some cam lean.
Now I'll quit and defer to the real "X" gurus. They would be Scepterman30 and Copterdoc. Let's see if they are on the ball.
