I asume you are talking about Cobra Craig?
I'd say exactly the same as Kev... he's quite a clever chap
201 may lack a little on power steering but shouldn't be as bad as you describe. Are you running the new cut staggers? or old staggers that have been cut, if you are running the latter this may be your problem.
I would also agree with Kev about Vega conversion. From what I have seen of the car it makes the car more settled in general on the bumpy astro and gives a little more steering on power.
IMHO car of choice in the dry would be Vega 201 and if damp/wet TRF 201
Just wish I had either
LOL
For now I'll stick with the B4.1
