I did some rough calculating involving heavy arrows flung from a 29" DL Allegience pulling 70#s, and came up with a mind boggling numbers. Having fallen into this trap before and being fooled since many high performance cams don't seem to be as efficient at heavier arrow weights, I emailed Pat to see what the AMO is.

Pat told me they don't AMO their bows, but he did fling some different weighted arrows through the chrony and gave me the results. Doing some quick extrapolating from his tests to my desired set up, ponder this-

A 70# allegiance drawn 29" should fling a 550 grain arrow approximately 275 fps, for a whalloping 92 foot #s of KE, and momentum out the ying yang.

Easy to tune, easy to draw and hits like a mack fricking truck... Mercy.
