I'd forgotten about this thread! Thanks all for the responses
I'm more or less decided on Bridgestone S21's. Not the ultimate sports tyre perhaps but sporty inclined, work wet and dry, and no tyre warmers needed (it's a track day, I can afford to wait a lap or two to warm them!).
First outing I'll probably keep the old BT023s on just for a run around and to give the oil a good flush. I'm in the slow group so no pressure (Rocki 8 May, say hello if you're there). Once I've blown out the cobwebs, put synthetic oil in and changed the tyres the world's my lobster
