Really the turnigys are a great bang for the buck and if you are just bashing, get them again. I have not been all that impressed with my SMC's at this point, had them 6 months and only used in 17.5 stock and mod sedan and already puffed. My turnigy nano-techs have better punch, are older and have more cycles and still have a lower IR and no puff.

If I was buying batteries again today I would run R1Wurks with Nano-techs as practice.
