After reading last years reviews I demoed the B2,at 177cm, in Whistler last January and loved it, so I took it again when we were in Tahoe in late March. Loved it again. Trouble is, I dont have much to grade it against, other than my old Salomons, which are not as good ! Surprise Surprise.I am 6 ft and 185 lbs and wanted to go shorter than my Salomons(187). The next size up from 177 is I think 184. For me I would say go for the B2. Over here in Europe the B1 is not, so far as I can see marketed as an alternative to the B2, but its baby brother(or sister). I cant say that I noted it being iffy on the groomed runs, but each to his own. I thought it worked well over a variety of conditions eg groomed, bumps, crud, powder and therefore was a good candidate for one all round ski to do reasonably well in most conditions . Like it seems the US it gets good reviews over here as well .
