Those settings are perfect in my opinion.
In a roto league I played in last year, we used K/9 and K/BB as categories if anyone is interested in those, but I honestly like the categories that rhizzo has stated.
I would also be up for an unlimited move limit but would frown upon making daily moves for starting pitchers to keep up with wins or what not. I know it's hard to win this way anyways, but it is annoying.
If it would happen once a week, a speculative pick-up on Monday who gets shelled,, I wouldn't care if the pitcher was dropped on Saturday for a new starting pitcher, but if it's an everyday occurence throughout the season, I think we need to address it now and state that it should be banned if used in that manner.
