I am shooting a Mathews Legacy set at 63#, 26.75" PSE Pro Comp 300 (7.8G per inch) a ez crest wrap (10g) nock (13g) insert (12g)- shooting 265 fps. I would like to know what my KE is, I have always shot steelhead 100's, and want to make sure that I am still ok. I have never had a problem with my old MQ1, Q2, or Ultra 2. They were all 70# though. Hope someone can help. Thanks
