What heat sink to use on Neu?

Unfortunately its going to be a 1/8 electric race a run what you brung sorta thing, buggies, truggies and MT's so I won't have to worry about nitros I will be on equal playing ground with most others. I assume most others will be running Castle MMM combos a few of the Novaks and maybe in one or two of the new Tekins it guys can get their hands on them.
