I am working with the new LineJammer 250 arrows and was trying to get the spine/FOC/weight right for my Bow. Does your program have these arrows listed yet? I currently am shooting a 28"shaft with a full size beiter (18 grain) a protective colar (5grain) 100 grain point and 3 1.6" vanes. Total arrow weight 342 I am shooting 28"/60 lbs Old Glory. Arrows are shooting like darts BUT @ 270fps I am looking for 15 more FPS. I am going to go up in Lbs and try to see if that works but I do rely on the spine charts alot to get me in the ball park to save alot of time. Thanks for the help. Later Junkie
