I see what you mean about the search function. If you just put in B3 nothing popped up. But if I put in B3 and Billiam, I get a bunch of hits. If you put in Rossi B3 you get even more. So I don't know. Try B3 and Billiam and you will get a relevant set of hits that describe the ski.
I am deciding between the B3 and the new Volkl AC4 for my next ski.
