Well snow conditions are always a crap shoot. You got lucky with Big Sky. It could have just as easily had been no snow in weeks while you were there with crappy cold conditions.
Hopefully you hit a storm cycle. T-ride is a remote area and I am sure it's not very busy. So there should be plenty of stashes around. I also doubt the smaller size of the resort is going to matter. It's still more terrain than you'll be able to ride in the time you are there. I know that resort packs a whole lot of bang for it's buck terrain wise.
