Treeski, most people in Tuckerman Ravine on any given weekend spring day don't know what skinning is. They'll walk up in sneakers, hiking boots, or even their ski boots. They also don't appreciate the risk despite the many signs along the way about avalanche, ice fall and crevasse dangers.
I once hiked up over the lip and heard 'you can't see where you are going' from a kid that had just turned around so see where he was going to ski. He had just crested the lip and gone from 50+ degrees to 30 degrees or so. He was gripped. It is very steep in the Bowl. The gullies can be less steep, but they are also narrower with rock walls. Hillmans is the most consistent pitch and fairly wide most of the way, but one slipup and you may slide for half a mile. I believe there was a video of a good long slider (above somewhere).
kletter1man, skinning up the Sherburne trail is how my friends and I would access Mt. Washington. I haven't been on there in 15 years but I don't expect they have changed their methods. We would be going up long before anyone would be thinking of skiing down. If you are skinning up when people are skiing down, you are way too late and deserve ridicule; for being in the 'crack of noon club'. Also, see comments about 'Sherbie' above.
The only way to ski terrain that isn't too steep on Mt. Washingtion is to stop hiking when the pitch becomes too much for you. You don't have to hike up far to get to 40+ degree pitches. The Bowl starts of nearly flat and gradually gets steeper and steeper. Putting your skis on will require serious consideration unless you choose to mount up where someone has already built a shelf or you are experienced at putting skis on while standing on steep pitches.
Ski choice is, of course, a matter of personal choice. Unless you are skiing down the Sherburne, you won't need to worry too much about rocks. Ideal conditions, in my opinion, is about 1 - 2 inches of corn. Below the corn will be hard pack or ice. If you are a skier that makes 5 turns down a 700 foot bowl, then big skis would be in order. If you prefer to control your speed and make lots of turns, carvers would work well. You just don't know what conditions you are going to get, though, until you get there, so be prepared to deal with anything. You can get to HoJos on a brialliant sunny day and start walking up to the Bowl and end up with clouds and snow. The skiing can change from lovely corn to hard coral in a short time. Expect the worst and you won't be disappointed. Hiking for your turns only guarantees you'll get good exercise, not good skiing.
Another hazard that is mentioned less frequently is other skiers. If you are skiing in gully or chute or even the wide open Bowl, you need to be aware of those above you as well as below. Out of control skiers are common and you don't want to be in their way as evidenced by the speed and violence with which they may fall, as evidenced by Tog's videos.

This is at the top before the actual gully. It gets a lot steeper than what I'm on at this point. Narrower, too. The background is the looker's left of the Bowl, at about the outrun of Left Gully. This picture was likely taken in late spring.
Skiing Mt Washington is an experience worth undertaking. Whether it is a good or bad experience is up to the skier's level of preparation, expectations and backcountry skiing savvy.
