Has anyone tried that new MIP 17.5 Pucks Drive System yet? I run my 17.5 buggy blinky in the local expert mod buggy class since the local 17.5 class is dead and in order to keep up, Ive done everything I can think of to make the drive train lighter and quicker (alum. top shaft, alum. pinion, triad, ceramic bearings, shaved diff gear and idler) but the price of the MIP kit is making me think twice. I just wanted to see if anyone is running it and if they like it and if it really makes a difference in terms of acceleration and deceleration.
