Tremolo, we will have to wait and see what kind of speeds you get with the CE Maxima's. I'm thinking you'll be in the 250 FPS range and if that's the case you will match your current KE according to BowJackson's KE calculator. Your current setup of a 463 gr. arrow traveling at 220 FPS produces 50 ft. lbs. of KE. After you get your arrows cut and fletched by your local shop hopefully they will allow you to shoot a few through their chrono. Don't forget to have them weigh them too.
