I will have to opinion that earlier season skiing on Mt. Washington is much better than late skiing in Tuckerman Ravine. Earlier there is much more terrain to choose from and you get a decent run all the way back to the base. Perhaps the nicest benefit is that you can skin up the Sherburne trail. Way much nicer than hiking.
Defiantly do not limit yourselves to Tuckerman Ravine. It is not the best skiing - just the best at holding skiable snow late into the year. Before you venture up be sure to check the web for the official weather and avalanche conditions. Things can and do turn real nasty up there.
Here's some footage from last year. Skinned up through the Ravine but came down the hanging valley between Tuckerman and Huntington. We then skinned backup the hiking trail to HJ's and skied down the Shurborne.
