I like mine, one thing i noticed was that they seemed to get considerably softer over time (like over a season and a half with heavy usage). This wasn't necessarily a bad thing, but on jumps it made it a little more uncomfortable if you landed too far back seat. I'm not very good at technical rail tricks so can't say much on how their width affected them, but they definitely had some serious rail time on them and the edges and bases held up great, no edge cracks or anything. As for powder, they work ok, definitely not ideal, mine were center mounted and after a while in the powder it became quite tiresome to be leaning back so much all the time. When jumping or dropping into pow I had to be very careful to stay back seat enough other wise the nose would drop like a rock.
All in all, I used them as my do everything ski for over a season and I liked them and recommend them, but they really are more of a park ski than anything else.
