Yes, definitely use a different system next year. I'll defer the decision to someone else... I check once a week after the games to see who's catching up on me, and I have a bit more in-depth look in deciding who to transfer at the beginning of the month.
It seems to be working pretty well for me so far. Obviously knowing a bit of the ins and outs of the way this fantasy football league works is as important as football knowledge itself, but I imaging that would be the same regardless of which system we used.
