to many choices to little time
as for the mtx and a shoe 2 speed Kawahara has it covered for us so what ever. I'm keeping my mugen till I see some of these new rides perform for myself.
I have heard that one of those cars that is fairly new is going through a redesign already. I will refrain from saying which as to not upset the applecart.
If you like the X ray get the impulse pro.
