Definately great information. Thanks for taking the time to go into it as well as you have. I am not exactly sure either as far as the info the "Birth Certificate" says. It is a tag followed with other info written in w/pen and other info includes. "Draw Wt." >1 (this is in pen) "Arrow Wt." and in pen 350gr "Draw Lt." and in pen 29 (although I have had it adjusted to 28 1/2 "IBO" 296 (pen fps, then who built it and who tested it. Again, thanks for all the information and once I read it over thouroughly iI am sure it will be of great use.
