Higher pinions = safer MMM's? Or no? Someone's lying....

I could swore that it was determined here that the higher the pinion count on the MMM and motors used on the Flux resulted in bigger loads and more chance of frying the ESC as a result? But now HPI apparently is stating that going to the 25t vs the 20t is the safe way to keep from hurting the Castle creations MMM and motor. What?? Wasn't here that we determined the higher loads were resulted of the higher RPM as a direct result of increasing the pinion tooth count which resulted in a higher chance of MMM failure, along with voltage spikes

So....wtf. What gives Castle? Who's right, whos wrong here?
