I am testing some now, 23 5/8" long 2213's. Have been shooting them out of my Phoenix at 294 fps at 0-40 yds. with 2" Blazer vanes 100 gr. pts. or B'Heads. So fer fer they have been real accurate and group well. They were some older arrows i used when i had an overdraw on one of my compounds. After i cut the tapered end off i got the length they r now. I can always heatinsert, remove it and cut shorter and stiffen up spine!
