Brushless TNX suggestions?

[Dagger Thrasher]

Thanks for the insight guys, it's been helpful. It depends on what I can afford at the time really as to what motor I get; I've been also thinking about a 6S LiPo 8/9XL setup, but that'd of course require a beefier ESC than the MM. So many options! Assuming the MM gets the software update, do you think a Neu 1509 would be up to the job?
I've never had a Neu, so I don't really know what the 1509 would be capable of. Obviously a 1512 or 1515 would be better, but I can't really bring myself to spend over $200 on a motor. Bear in mind that this truck would be a basher, so I'd like a top speed of 45 to 50...I know that's asking a bit much from 4S.
