10 is the best number IMO, but I've done 8-man leagues before. Everyone has a great roster and there are decent guys on wavers, but it's still challenging. With 12 -14 you start playing 2nd and 3rd team players and for many teams it simply boils down to one or two early season waiver moves (or misses) that makes or breaks a season.
