Griffin....mod them as in how.............................................
I agree with you said about the pletts , there quality is second to none , I have 3 brushless pletts and three brushed all ( 355's )
With water cooling on-demand you can draw ridiculous amount of Amps with smart layout. All the same more Amps, better cooling.
-I do love brushed 355-series, two of them were placed in my neighbors barbi-jeep you can imagine what a joy it was in conjunction with optima battery :)
