I have set 11 in our current league 3... they are admittedly overachieving but they are off to a hot start at 36-24.
I had to trade away some big names... e.g. Trammel, Sandberg, Boggs... but then enlisted Pfiester, McClain, Maris, and Dick Allen as better complements to my stadium (Exhibition)...
The real problem I had with set 11 is the stadiums believe it or not... I wanted to try something with more of a pitcher's park, but there's not one evident in set 11.
Case in point as to my "over achieving"... Tommy Boggs is 7-0 in 7 starts and Craig Lefferts has 22 saves in 60 games... Yeah, those stats won't last.
