I just finished a HR team at Coors that went 85-77. I have three HR teams going now, although they are more hitter's/OBP teams than pure HR teams --Verisimilitude is 33-21 at AFC, Big Fly is 12-9 at Coors and Trajectory is 23-22 at AFC.
I find it very hard to push a HR team over 90 wins or to get it to do well in the playoffs (if it even makes the playoffs). The only HR teams with which I have had success recently is when I load them up with three or four Ruths (usually `29, `32 and `33 and maybe `17 pitching). One of those won 99 in an OL and went to the WS a few months ago.
