Since Pigger and I started hunting together, my go to arrow is a:
60-65 back taper Shurewood shaft, 3-5" RW feathers, tipped with 145 Eclipse Broadhead. Pigger and I'd have used it on on everything from grouse, deer, mountain lion, elk, moose, and bison. Don't see much reason to mess with all the new fangled stuff.
My personal observation: Dead is Dead, the critter don't care much how popular the setup is. Shoot the setup that recovers the quickest, flys the straightest, and hits where you want it to.
