In reply to David Cowley:
We reviewed the Super Couloir gloves last year. They're very good:

Of course, as in footwear, the fit will determine how well you get on with any glove, so you've covered the most important factor already.
Warmth-wise they're about midrange in insulated glove terms I'd say. Not too thick for climbing/gear fiddling, but probably a bit under-powered (as all such gloves are) when it's particularly cold/windy, and for long belay duties. I'd use them for climbing and carry something thicker for the cold.
Dexterity-wise I'd say they're about midrange too. Fine for punterish low-mid grade climbing (that's all I do) but I can imagine harder climbing needing something a bit thinner and more nimble. But then you'd definitely get cold hands. No one has yet invented the perfect do-it-all winter climbing glove.
