Man, after shooting the X-Force last nite, I would think if you had any problems with pulling a bow back you would not want that bow. It's a monster to break-over and has little to no valley. It's fast, but at what cost....at what cost. I shot the Marquis as well, and it's pretty smooth, not a bad bow. I have yet to shoot the guardian, so I have no opinon on it. Congratulations and good luck.
