Tobamory the cars you have listed are all great cars and have proved themselves at all levels. 99% of people are running mid motored cars now ! What are people running at the club you race at ?
Why not go for a car that can be converted with kit parts
like the Durango dx210, Yokomo bmax2, Kyosho RB6 (yes it is expensive, but quality)
Nothing wrong with the other cars you have listed either but its up to yourself.
I'm guessing here but you being in Leeds you are close to the respected MB models in Otley speak to them for more advise.
