RE: b-heads for elk
Magnus stingers, Muzzys, Wasps, Rocky TI's Nap's new Nitron and Crossfire, etc. The list goes on and on as far as high quality heads go. Pick a weight, tune your bow well and use a high quality head. With your shorter draw length I would consider a cut on contact two blade head to maximize penetration though. Stingers, phantoms, Zwickeys,bear razorheads G5 B52's are all excellent choices.
