I'm pretty sure that is the case I demoed the 99 and really liked, and figured the 90 would be a great early/late ice ski.
I am betting they are base high. Guess I should check with the shop at some point to see if they started tuning them yet, but at this point the snow is fairly soft, and my E100s are so good on most terrain, I probably won't think about a skinnier ski until April. They really are not too bad on ice, but you have to work a little harder, which is why I bought the MB 90. In hindsight, I probably should have just bought a skinnier Enforcer.
