Ron,

Something sounds wrong with your K.E. figure. To get that, you would have to be shooting that 425 gr arrow at 325 fps. You're a full 1" less than IBO draw length and shooting a 75 gr heavier arrow. Are you sure of your speed? If a Black Knight is that fast, then I'm impressed.

Another question. Can you bowhunt with a 5.25" brace height, if you're wearing heaving clothing? It seems likely that the string would hit your clothing very easily.
