My local tyre place is a Vredestein dealer and he highly recommends them (he would) but so do quite a few forum members. They are good VFM and some of the reviews are excellent.
Also the local tyre guy told me about the Hankook ventus v12 evo k110's (what a mouthful) He said they were very good, and at £80ish each they were not to be missed. They also are getting some great reviews.
However, I think my next set of tyres will be the Yokohama Parada spec II's. I was VERY impressed with Nathan's, when he took me on a brown trouser lap of the Nurburgring
