Personal descision! These are some of the toughest choices one makes....especially if you're planning on holding on to this bow for some time.

If it were me, I would choose the SQ2. I am biased though, I have an FX and love it. Next bow will be shorter and faster. It all comes down to your preference....shoot them some more and make a descision. All the bows mentioned are quality equipment. I know I'd be happy with any of them.
