In regards to spin, I just had a match where my front line spinner took 11 wickets in a test match, no real surprise there, so I've decided to just nuke my spinners attributes and they didn't take a wicket in the first innings of the next match, but still went a reasonable economy. So if in the 2nd innings they pick up a few wickets, maybe that's just what you have to do with spinners, just make them really only as good attribute wise as part timers which is around 45-55.
