I'm using one Graeme, as I've only recently ridden 3 meetings in 30 years I'm definitely not an expert.
My first impression was that it was a good tyre, as my race pace has built up I'm not so sure, mind you the last meeting a few weeks ago it was slowly going flat and I was all over the shop in my last couple of rides.
The word is that the tubeless Michelin is the go but I'm going to turn mine around before the next meeting and see how it goes.
Which brings up another point, they have a Vee groove pattern and I've seen them used both ways, not sure which is correct, I did have mine fitted at a dealer but suspect it is on backwards.
Don't forget the Mitas is now available, there's a thread on here somewhere.
