B64 or B64D ????????
 

I know the B64D was launched first but I will be racing mainly outdoors on Astro tracks with the occasional grass track session and indoor sessions, am I better off going for B64 ?

I don't want to make an expensive mistake.

With a change of springs, front roll bar & thicker centre diff fluid, the B64D works perfectly well on high grip astro. Then works very well on grass.

From what I've read on the forums it looks like the B64 might have some upgraded parts from the B64D. I know they are talking about making running changes.
