You guys have to get over this "tucks isn't safe until the spring" bs.  The level of danger at tucks changes on a day to day basis.  The overall dangers change on a seasonal basis. e.g. the dead of winter has heavy slab and multi-directional wind dangers, the sprint has crevasse and wet slide dangers.
Needless to say, Killington glades is not backcountry as you've already stated.  It's not the difficulty of the terrain, but the dangers you need to be concerned with.
Don't take this as an insult, but you don't seem to have any backcountry training or experience.  I really recommend that someone w/your experience stays away from tucks until late April when Tucks becomes more crowded.  While not always true, the more people that hit a slope, the safer it is.  Conditions change throughout the day, so frequent travel is only a reassurance.  However, if something slides, you'll have more spotters and (hopefully) patrollers there to track you down and dig you out.
It worries me when I see people climbing straight up the gullies in 80 mph winds b/c there's 2 feet of fresh blown into the bowl from the night before.  Those're the people Darwin takes care of.
