If this is about what I think it could be about, please don't copy Moto Arena....
Anyway, onto the point.
My favourite is WLRC. Its the right size for 1/10th TC, the layout you need a quick and stable car through the sweepers but one that stops with pinpoint accuracy for the twistys. The track is wide enough to race side by side without the guy infront having to make a mistake, yet the markers make sure you know when you've got it wrong.
Good burger van too. Thats most important.
I used to love Bedworth too, though haven't driven a TC around it for a long time.
