Bought set of Conti TS850 for just over £500 six years ago for my old FR170 and have been using on my FR184 for the last two years only when it looks like temps below 7 deg so not for more than a few months each year (I live in London). I bought them after watching some youtube vids on winter tyre performance and after some grim snowy drives to work 40 miles away. I have to say that they don't just help a bit - they are in a completely different league when it comes to snow, so much so that it almost seems unreal that tyres can make such a huge difference. Earlier this year I had to fly from Gatwick on the worst day when we had "the beast from the east" and there was a lot of snow and slush on the M25. There was no issue whatsoever.
I am lucky enough to be able to choose between the Leon and a TT and if it looks icy the winter tyre equipped Leon is so much more secure feeling than the (Quattro) TT and in snow would leave it literally standing. In rain in the summer clearly it's no contest the other way around.
I only have experience with the Contis which from all the reviews are the best - the same set of wheel/tyre is now about £800 on mytyres.
