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.
This just doesn't seem possible to me for some reason. If you get 275 with that arrow weight I would suscept that the 29 inch draw length is not really 29 inches AMO. I would have to see it and measure it myself to believe it..
good luck at any rate. I'll bet it would be quiet though.
