I skied at Mt. Washington BC in its early days around the time it first opened. BEFORE they developed the "Outback".
I didn't post because my experience is antiquated, but as you have nothing better to go by....
The runs at mount Washington are steep, but the snow does slow you down quite a bit.
I think I ventured an excursion or two over to where the outback is now one year, and found the thrill not worth the hike back. I was going to go back again the next year, but they were working on it and I was discouraged from going that way, until they were done. Unfortunately I haven't been back since they opened it. Who knows, maybe they cleared up a lot of runs that weren't skiable before.
If you look at their trail map, you will see at the top of eagle lift on skiers right of the lift there is a little cliff. It used to have a warning rope. IIRC I used to start at that cliff and ski down somewhere (it's -or at least it was hard to tell exactly what run you're on 'til you get further down) between west basin and westerly. I could be wrong, but I would say if your comfortable with that area (chimney, powderface, westerly, westbasin and king geroge) You don't have to worry about much. If you want challenging lines, there is another cliff on the other side that was also roped off, but had a few skiable lines (depending on tree growth they could be gone or maybe there are new ones now), that I found worth the hike back. I don't know how Ski Area Management and CSP would feel about you ducking that rope these days though.
As far as skill required, when I first skied there I had almost none, and I seemed to be able to manage without falling down after the first three days of getting used to the deep snow. (on old long skinny Dynastars GS skis)
