FloodGrapher 2 Jar?
I'd just use real battles and improve my score vs a test bed of like 100 bots. I use BedMaker, which I think needs updating to communicate with LiteRumble. I also posted some for Tkiesel a while ago over on User talk:Tkiesel, if those are of use to you.
But MC2k7 should still be useful if you prefer that kind of thing.
