A quick question steming back to the question about changing out cams on the 05' alleginace to the 06' modular cams.

Are the riser and limb geometry the same for the 05' and 06' models of allegiance? Or did they completely revamp the alleginace for 06'? If they are the same I don't see any reason why they wouldn't interchange with each other. Might have to also buy new limbs????

Also, how smooth are the fast modules on the alleginace?
