Thanks for all the help. I just ordered the Blackhawk on Monday and am wandering about this infinity cam letoff adjustabilty thing. From the previous post I semi-understand that the shorter the draw the less letoff, the longer the draw the more letoff.

SO, if I shoot exactly 29" and I ordered a bow with a 29" module, where does this put the letoff????
If the letoff allenbolt peg is exactly in the middle, would that make the bow have a 72.5% letoff? (halfway between 65 and 80)

Seems to me a bit of a stretch to name this came " infinty" when you have to rob Peter to pay Paul.
