RE: Mathews SQ2 with a Legacy cam.
I don't think this is possible, because Mathews makes each of their cams specifically for that bow, so they tell a lot of people to not use cams from other bows on theirs, like the SQ2 I think has the same Straightline Maxcam as the Q2, but they made a mod. to the Legacy cam (it is called the Straightline Maxcam 3!!) the one on the SQ2 is #2 Maxcam! It would also void the warranty of the bow!
