i play roto for competitive leagues and h2h for the fun ones. i just can't abide weeks where someone like nick johnson gets 3 random SBs, causing my downfall, when i really care about it. but if it's a fun league with friends, no biggie.
the most frustrating thing in leagues like that is that there are like 10 guys on waivers i'd like to add, but everyone on my team is already too good to drop. (that's the league where i have pat burrell, shawn green, and brad wilkerson on the bench.
