advantages to a longer ata are in stability/accuracy. the string angle is less dramatic as which makes the pinch less. A longer ATA will give you a more stable hold on your bow. of course this is subjective to different people and some people could certainly do better with shorter bows. but in theory, longer ata is better for shooting. i owned a general and i can tell you first hand, that i can shoot more consistantly with my 101st. hitting an x is hitting an x but with a longer bow, most can do better.

short ata is nice for hunting and there is no argument there.

btw, im 6'3" and about 260#'s and the short or long has never made a difference to me in that aspect. i shoot a 29.5" draw with a d loop.
