Well I made my decision on this one and ordered Vredestein Wintrac Xtreme winter tyres in F 225/45/18 and R 245/40/18.
Hopefully they'll be good. Haven't heard of anyone having any problems with thm anyway.
My choices were pretty limited. Goodyear were out from the beginning, as they only had Ultra Grip Performance for the front, and Performance 2 (which is a different tread pattern) for the rear. They also had no stock coming into the UK this winter.
Dunlop (owned by Goodyear) were also out, as they had none of their Winter Sport M3's or 3D's in stock in the UK, with no plans to make any for this winter.
Michelin also didn't have any of their Pilot Alpin PA3's in the country, and said I would need to wait 6 weeks.
That only left Blizzaks and Nokian WR G2's. Both of these tyres had had mixed reports regarding dry weather handling, as in being too squirmy and soft etc.
I have never heard a bad word about the Vredestein's, so decided to go with them. Will get them fitted at the end of the month, and let you know how I get on!
