Ok....so you have a 46# selfbow.  It is 64" long.  Tell me what arrow set up you would make to have the heaviest arrow with the new EFOC as reported by Dr. Ashby.  Wood, carbon, or aluminum?  And we need  from 26 to 28 inch arrow.

If it was Me?

Birch or Ash shafts 45-50#
160 grn Snuffers
tapered from 11/32 to 5/16"
wrapped self nocks

cane shaft, osage foreshaft, long/slender stone point = EFOC 20%
