yea, Spraddle creek is a grunt, but it is a beautiful ski tour. You said some members of the group are fine with climbing, so just get an early start and take is slow and steady. Eisman is one of the premier huts in the state, no doubt about that. Great skiing right off the front deck. Great terrain to the north of the hut, although it goes to a South aspect and can be a little funky when baked (or it could be corn). There is some nice North aspect stuff to the south and west of the hut also. Just beware of some avalanche potintial in that area. You could spend many days at Eisman and still leave plenty for the next trip.
I'm a little confused why you would want to use a snowmobile if everyone is able bodied. I know the the Tenth highly discourages use of snowmobiles to get to huts. Getting to the hut under your own power is a major part of what the whole experience is all about. I ain't supposed to be easy! I know that might sound elitest to some, but there are plenty of "artificial" power assisted forms of entertainment out there. The huts are one of the few remaining exceptions to that. If you follow that ethic, I think you'll have have much richer experience, plus you'll burn less gasoline and not pollute the air. [/u]
