I won a ring in ATG5 in Vets '75 using an all switch hitter team:

Anyway, the switch hitters really messed with HAL's bullpen logic. You can burn through RP specialists pretty quickly with an all swich hitting roster.
On the pitching side, I went only with pitchers with good hold ratings (-3 or better) to counter Simmons' arm. Interestingly I still gave up 143 SB.
