Boss,

Send me your email and I'll send you a spread sheet that I've been building that will give you a very close idea of what speed and KE you can expect from your setup. While it is not perfect for every setup, it will at least serve as a guide. You can play around with draw weight, length, arrow weight, string accessories etc....

Based on what you said from your setup going on the low end of Bowtech's IBO speed rating (just to be conservative) it shows you to be at about 250 fps & 56# KE.
