2wd 1/10 buggy options

[tintinontour]

Gentlemen, I'm looking for advice and opinions...
I'm currently racing a 4wd, but getting a bit sick of being in the 4wd minority, in this 2wd world. Thinking about getting a competition 2wd. I am mostly planning on racing indoors at Silverstone and outdoors at the glorious track A1 Racing have in Grantham, although I will periodically race indoors at worksop as well, and who knows what the season will bring? So, thinking something that works well on high grip tracks, but I would like about something that works well on lower grip surfaces as well - without having to shell out an absolute fortune on extra parts.

So, my long list is:
Cougar KF
Associated B5M
Yokomo B-Maxx2 (like that this has rear and front motor options supplied in the kit)
Kyosho RB6
Team Durango DEX 210

Any thoughts or advice gratefully appreciated.
