I run MIP CVDs in my rear, but have RCBest ones for my front and center.

Great price. I've heard a few people breaking RD Logic ones, but never heard anything about those so I decided to give them a try. I'm running a 9918/9L and they've lasted for 2 battery packs so far. Hopefully that's just the first 2 of many runs...
If you plan on running the XL series motors, which have much more torque, then it MIGHT be a different story. I guess it also has a lot with one's driving style...
Other than that, UE and MIP are supposed to be the best
