here's the deal with the mini rocker in the Seth's: it's only in the shovel of the ski, the tails are traditional camber... if you put both skis base to base and totally flatten the camber (making the bases touch completely), you will see a slight flair in the shovels - it starts about 12-15" from the tip of the ski, and is very mellow... the tips curve up normally where you would expect them to, but the there is that area (about 10 or so inches) of mini rocker up there...
as far as skiing them on the east coast, no problem at all - yeah, it's 98mm under foot, but it's also a total quiver of one ski - park, pow, groomers are totally legit...
