Welcome to VT!
If conditions in the glades are good (as of Sunday, they were decent and you can still find a stash here and there)
Test Pilot is probably the most wide open glade. If you enter into it early it's tight, then fans out really nice. Not a real challenge, so a good first glade.
On the other side of the trail you have the Kitterbrook Revine. One of the best glades on the mountain because it has a real fun natural half pipe in the middle. When there is powder, you can find some nice lines in there.
Both have a bit of a run-out. It's not horrible, and you don't have to use poles, but it's not great either.
My personal favorite glade:
Diamond in the Rough
Seems like it does not get the traffic the other get and its a bit more challenging. You can also do laps in it via URSA high speed 6 pack chair which is another reason I like it.
Best secret glade:
Left on Upper Lift Line. There is always pow in there.. Also - off of Work Road. Problem is you might have to walk back a little bit, but the pow is always fresh.
