I have been using 2213's at the shoot fer the speed. I have 17 of them fixed up 22" long.Alum. incerts inbehind 75 gr.pts. 2" Blazer vanes and cut off alum. incerts as a flat nok in back.Weight about the 350 gr.area. I had 18 but a limb ate one on this past shoot. They're fast but not sturdy enough so i am going to 2216's. They're the same setup all the way and i will drop some speed. Will try them out and see how they work. DNK, yer Flemish Fast Flite string is doing well and has about 100 shots on it now.
