Don't worry, most on here giving advise haven't shot them all either.

I have shot the drenlin and switchback and like the switchback more just because of its limb design.

I own a commander and love it and highly recommend it for a draw like yours. But its heavy. Noticably heavy. I have shot the 101st and if your a speed freak, you won't be happy unless you have this one. But, the commander is so much more quiet and shock free. I will take that over the 101st
