Jerry,
You know I didn' t think of it at the time of my last post but you are right. I' d like to see some sort of standard for showing spine also. CE has their arrows numbered 100, 200, 300 etc. Blackhawk has who knows what, depending on which ones you have. Frankly, I like Easton and Beman numbers. They tell you the actual spine deflection-- 500 equals .500; 340 equals .340, etc. Sure would make life more simple for us consumers.
