I always think with ESCs you should get what you can afford. If budget is tight then go for the lower spec and if you can go for a TC2 then great, at least the TC2 doesnt have too many adjustments to confuse the hell out of you like many other ESCs do...
I got a TC2 and its great, but recently I got a MRT VXPro, why, cos it rains here and it is small... if water is not probs than you guys are spoilt for choice!!!! LRPs are great speedos and they are very smooth and easy to use. Plus the lower range you dont need t oknow how to solder, of course I prefer to do my own wiring.....
