Like a lot here I've been at archery for more than 4 decades. Like several, but fewer, I've also only recently returned to traditional. I owned a relatively rare 56" Grizzly back in the early 70's. I was a righty then. Paid $60 new at the Tru-Flight shop in Monticello, IN. You have a very nice bow!
I love to tinker. I love to "game" with Stu's Calculator for hours at a time. I care very much that my broadheads and field tips shoot the same, BEYOND the distances I'll shoot at game.
That written, I'm going to share something that many will consider over simplistic. A good friend of mine, and equally devout archery nut, gave me this advice about 14 months ago. Because I would be shooting in the mid-40# range he advised I try Beman MFX Classics in size 600 (smallest diameter they make). My arrow weighs (with 100 grain broadhead and 75 grain insert) only 415 grains (2 complete pass-throughs on whitetails this past season). I'm fletched with 3, 4" parabolic feathers (I'd go longer if I had a 28"+ draw length).
My arrows fly like dreams and you can't tell whether I've shot a broadhead or field tip in the target. I shoot this arrow in recurves from 45 pounds to 50 pounds at my 26" draw.
I have hundreds of aluminum arrows and shafts -- mostly 1916 and 2016--several are Easton legacy shafts still in the packaging. I love the toughness of these MFX shafts. I've been shooting 2 dozen for 14 months. I've broken one. I shoot at least every day, twice today... so far(I'm test-driving a Robertson Fatal Styk). My feathers are wearing out and I've destroyed several nocks, but the shafts (except for some finish chipping in too-tight groups)are the toughest I've ever shot. I just obtained 4 dozen more of these, 2 dozen 600 and 2 dozen 500 as I'm going to bump my set-up to get to a 500+ grain arrow.
Maybe this shaft won't work for you as well? However, my buddy saved me a lot of trouble, experimenting, and likely some frustration by passing on his experience to me. That is my hope for you.
