I have a few pairs of Kombi gloves, which are my main gloves during ski season, and some other stuff. I ws really impressed with some REI gore-tex gloves I used last season. They made it through a downpur without soaking through. The Kombi's are usually only good for a couple of hours if I ski in a hard rain. I also used some Outdoor research shells on one rainy day, and I should have had an insulating layer under them. One really good way to improve a glove is to use a polypropelene glove liner. I only use mittens on really cold or really rainy days, and they work well for either. I see no reason to mess with lobster gloves.
Some other brands that I have had good luck with include gordini and reusch, and I know a lot of other guys who use Swany.
