Gordy, not to sound like the smart a-- that I am, but DUH! I know they are light but a guy that was not blessed with the arms reach of a Gorilla has to what he can to gain every fps. As you well know I don't shoot IBO tournaments so to me IBO minimum is not a factor. Also, as far as being underspined I don't think so according to the chart at Brownlee's Bow Works; borderline/redzone yes, but not dangerous especilly since I lightened up the point to 85 grains. Come on over to the back yard and give it a try, and remember to bring that new Patriot. I promise not to bust any more of your nocks!
