Speaking of fun platoons, how about this one in League Park '34 at $120 mil:
$6.70 mil Juan Gonzalez .293 48 101
$3.88 mil Ted Kluszewski .259 17 41
Combined Gonzo & Klu .277 65 142
From the looks of things, Gonzo had more "fun" than Klu.
I use a platoon at DH on a lot of teams, but I've NEVER had my platoon DH against lefties (or righties for that matter) get 100 RBI except for Gonzo. I'd have to look, but I don't think I've ever had a platoon DH get 40 or more HRs either, except for Gonzo above. I spent a bit more on that platoon than Andy, but the cap was higher, too. Since Steven always asks for it, here's the link to that team:

$2.02 mil Art Shamsky .269 16 50
$.93 mil Lou Piniella .264 12 50
Combined .267 28 100

$2.02 mil Art Shamsky .266 12 41
$.93 mil Lou Piniella .290 16 47
Combined .279 28 88

$3.88 mil Ted Kluszewski .268 35 89
$2.12 mil Joe Charboneau .289 13 31
Combined .276 48 120
http://onlinegames.strat-o-matic.com/team/811604Here's Klu and Joe Charboneau again in League Park '34 at $140 mil, with similar numbers
$3.88 mil Ted Kluszewski .275 27 71
$2.12 mil Joe Charboneau .261 15 36
Combined .269 42 107
http://onlinegames.strat-o-matic.com/team/385659Here's Jeff Burroughs and Lou Piniella in Minute Maid at $100 mil
$2,93 mil Jeff Burroughs .279 36 83
$.93 mil Lou Piniella .304 12 42
Combined .288 48 125
http://onlinegames.strat-o-matic.com/team/362678Here's Klu & Lou, my most frequently used DH platoon combo at $100 mil, in League Park '34
$3.88 mil Ted Kluszewski .333 16 69
$.93 mil Lou Piniella .289 14 51
Combined .312 30 120
http://onlinegames.strat-o-matic.com/team/362439Another player I've used with good results against lefties is $1.44 mil Mark Brouhard. I've also used used $3.22 mil Johnny Briggs against righties, but with mixed results. Klu gives more bang for the buck. I've also used Gates Brown at DH against righties once at $140 mil, with poor results, but I've seen him do well for other teams at all caps $140 mil and lower. I shy away from Brown, as many times HAL will let the platoon player bat his weak side when there is a change of pitchers, depending on the situation, and Gates has no chance whatsoever against lefties.
On smallball teams, I've had good results with $2.34 mil Phil Weintraub at DH against righties and have seen others use $3.17 mil Roy Thomas both ways at DH with good results. I've seen other managers platoon Weintraub and $.91 mil Jesus Alou at DH with good results. Some even use them as a LF platoon!
Some of the above numbers may be a little high for RBI and HR totals, as HAL will often use such players as injury replacements against both lefties and righties, which drives BA and OBP down.
