e-maxx brushless recommendations

Hello all, nice forum. I hope you don't mind but I would like to kick this horse again, lol. My plans:
Feigao 9l, 9918, 2 2s2p 6000mah lipos, fan, UBEC.

Uses: Bashing around and beating up on neighbors nitro
Wants: Fast!!! runtime better than stock (15+ mins)
Setup: Pretty heavy (lots of shinny stuff), CVD's--stock gears and boxes

Thoughts? Opinions? Recommendations? Greatly appreciated!
