Good base for a E-Revo build

[miniGranis]

Thanks,
As I plan to use Mikes new motor mount and the stock Revo tranny would it be better to use the Feigao motor with built in heatsink or should I go for an smoth can motor and adding the external heatsink ?
Also does it matter what brand it is as long as it's an 9XL (or 8 or 7) ?
Feigao/Nemesis/Wanderer are all listed as one product in the shop.
