My next setup

[nl12]

I am itching for another brushless truck, I will go with the 09 XT8 or 8T 2.0 but that is beside the point, I am trying to decide what brushless system to put in it. I will use Flightpower Eon 33c 4500 MAH lipos, these are my options:

6s, MMM, and Neu 1515 2.5d
6s, Tekin RX8, Tekin 1700KV truggy motor
5s, MMM, Plettenburg BigMaxximum
6s, MMM, and Neu 1521 1y

I am trying to pick one, I need to balance power, reliability, and cool factor, in my opinion you can never have too much of those 3 things.

What do you guys think?
