Snet is as good as any.
The run off goes something like this: tarmac, old tarmac (airfield), grass, crops, cow, road. It might take you 1/2 mile to get to the road past the cow mind, so keep her upright, stay off the front brake and never mind the speeds, the circuit was my first and I went grass tracking half a dozen times. Thought riding a bike was easy-peasy.
Mallory is good.
Brands is a little of everything and I would say more people bin it there than Mallory or Snetterton. Cadwell is a hoot and quite testing.
Rockingham a little featureless - especially if you have a pal along to watch.
Any of the trés £ circuits will be a waste of time and money.
On balance, the novice group at Mallory or Snetterton for my money (which it isn't!).
