Lydden for me
it's a great setting for racing - you can see the whole circuit and provides fantastic racing.
Brands is pretty good too but I loathe that debris fencing.
Mondello is good apart from the weather
I know what chunder means about Pembrey and Blyton being bleak - I'm not saying they're bad circuits (far from it) but the very nature of their location and the fact that they're old airfields means they're exposed to the best and worst mother nature has to offer. I'd imagine Pembrey can be a very cold place at times
Without the airfield circuits there would be a distinct lack of circuits (Pembrey, Blyton, Croft, Snetterton, Silverstone, Thruxton, Castle Combe - anywhere else?) so we shouldn't complain.
