With regard to the Superchief opening late, remember that its unusual location means that it takes a hell of a lot of snow to get everything connected. Takes more like 3 trails worth of snow to connect it to the mid lodge and base. I also don't think they want to spin the Superchief till Roaring Brook is open. It doesn't have a mid station and they don't want low intermediates from the lower mountain jumping on it and not knowing how to ski from the top.
I normally use that lift to take laps on anything Belleayre Run and skier's right. Otherwise, you're better off taking the triple. It is the only lift at Belleayre that lines up since it's the only way from lower to upper mountain.
