I use CE shafts from Walmart, all different spines. I've noticed the camo ones weight more than the black ones in same spine, also just a little thicker, guess it's the camo coating. I've settled on the 4560's, black, cut to 27", tip to throat of nock. I'm using a 160 grain Magnus Journeyman BH with a 75 grain steel adapter, four fletch 4 1/2" banannas, no wraps. They weight in at 540 grains total and they fly like darts from my Timberhawk TD recurve, which at my draw length is pulling right at 50#. They also fly well from my 56" Findish Hybrid at about 52#. They are also footed one inch with a 2216 shaft, and 3/8" at nock end. Great shafts. Haven't used them on a deer yet, but I'm sure they will do a great job if I do my part. I expect they will drop quite a bit at distance with that weight, but I won't take a shot over twenty yards, my optimum is 15, so I don't have to worry about that.
