You could definitely ski them at Jay or anywhere in VT, but I'd want another ski for most days there - they don't excel on hardpack conditions, but are still manageable. I'd ski a Seth and a Hell Bent if I could ski both in the east. The one day I skied the HBs was a warm groomer day at Keystone and they actually skied fine on the groomers, but if the conditions were a bit more firm, I think they'd get a bit squirrely under foot. The effective edge area does work for groomers, but it's really only meant for getting back to the lift in one piece, not made for all mountain skiing and typical east coast conditions.
The mini-rocker built into the Seth for next year is totally legit. It's killer for all mountain skiing, and excels everywhere on the mountain, but it's still only 98mm underfoot, so if you want a ski for huge floatation, the HB is the way to go, but it is a quiver-type ski, not an everyday ski.
