5.5 - 6.5 Brushless recomendation

[Brooks]

Hi Guys

What is the best and most reliable 5.5 or 6.5 out there.
Have seen the Novak Ballistics, they are bloody quick but expensive
What are the Lrp x12 vectors like, have read alot about them and seem to have a few problems

What do you people run in your 1/10th Buggys

Thanks in advance

Cheers
