RE: What bow for 31" drawlength
If you are in the 290s now, I don't think you are going to find much more speed with a standard weight arrow.
I am 6'3" and tried to shoot one of those "baby G's" it did not work for me.
From the options I see offered here, I think I would try the Ross.
The Ross bows are simply a pleasure to shoot.
If you can stay within 15fps or so and pick up the A2A, and get that smooooooooth Ross cam.
Might be worth the change.
IMHO
