Possibly a Bowtech Pro 40 Wheely or maybe a Hoyt Protec with the Xt3000 limbs. The Hoyt has specs of 41 1/2" axle-axle, 8 1/4" brace height, 75% letoff and still has good speed at 292 fps.

The Bowtech is actually 38" axle-axle, 7 1/4" brace height, 65 or 80% letoff, and speed of 304-312 fps.

I'm sure there are several others available, but these are ones I can think of right off the top of my head.
