Believe it or not, I have to agree with bowdoc on this one. An overdraw does not automatically make a bow less accurate or forgiving. At least, not in my case. I used a short overdraw on my old NFAA field archery bow which allowed me to cut my arrows back from 33 1/2" to 30 1/2" and, once I got it set up, my average scores jumped by a solid 35 points. I went from a high B class shooter to a middle A class, practically overnight.
While faster bows and light carbons might have eliminated the need for overdraws for MOST shooters, long armed sunovaguns like me could still benefit from using them. Put 'em down in the "Special Needs" column.
Low brace height bows would not make very good overdraw candidates though, and getting clearance with bows using high cable guards could also be a problem, so you gotta really think through the total package when considering an overdraw. Very many of the bows they're making nowadays would definitely be problematic, and Hoyt's Tec risers would be impossible to overdraw.
