MMM-UMCMTCMCMLMM is probably my strongest so far. Removing an M from the end also produces a fairly strong contender (which spends just slightly more time attacking, at the expense of spreading out a little more slowly in the opening).
It beats all of the built-in contenders, as well as Jonathan Whiting's fairly strong strategy. It doesn't beat Lythom's "Final Boss" from his blog though. :)
I haven't yet really explored what is possible with the "setup".
In any case, an interesting game!
