I'll repost this as the first time it disappeared into cyberspace...
Demo weekend at Bretton Woods just past. Sat: scratchy and crunchy earlier -- you East Coasters will appreciate the meaing of that. Then an inch or two by 1:30pm. I demo'd the B5 directly against a load of Salomons, Elans, Rossis, other Atomics, Ogasaka, etc. First B5 (162), then the other. Back to B5 then another.
Subjectively, the B5 is a panzer obliterating all crud, cookies, boilerplate and lousy conditions. In the little stashes of deeper snow I could find, the float was fine. BUT, and that is a big one, if run flat over cookies or crud, you are toast. You must remain on edge. That agrees pretty much with the consensus here, but it one thing to read about it and another to experience a little terror when going to fast and nearly losing it into the trees.
The Salomon SC10 (165) is almost the equal of the b5 across the mountain, even more sparkle in the groomed, but not the determined grip in the steep boilerplate. Both are heavy. Both exhibit minimal chatter. However the SC10 is much more stable when run flat -- on the same slope, in the same conditions, on the same day. It becomes a question of how you ski. Get lazy on the GS turns on flatter slopes and the b5 will bite you. It nearly got me until I received the message. The b5 might be a better ski for Killington conditions and the like, and particularly for the more agro skier. Less demanding ski areas (and skiers) might favor the SC10. Both are extraordinary and blew away the competitors (at least those that I tried).
I also tried the softer version of both (M:11 and streetracer 9) and both that in comparison the chatter and difference in grip was large. Still great skis, but .... Elan's SX was a great ski too, but a true slalom ski, neutral and dependable -- not the bulldog the b5 is.
This weekend I try the RX8 and then it is time to buy.
