Got a nail in my NS Front tyre the other day and as both front Toyo Proxes were pretty worn out, I decided to replace both, rather than have the puncture repaired.
After a bit of Googling, I went with 2 x Michelin Latitude Sport 3 from Kwik Fit at £325.24 fitted. Not cheap but no-one could do 'em cheaper, especially as Kwik Fit have a free mobile fitting service if you buy 2 or more tyres. It's a really good service this and I recommend it - wouldn't go to one of their centres though.....
Anyway, the Michelin's are excellent with loads of grip in the wet, which is where you want it most obviously. Don't think there's any difference in road-noise but they do feel more stable and compliant over bumps than the Proxes. Mind, the Proxes were well worn, so the Michelins should be better across the board.
