Agreed on the first tracks ticket if it dumps the night before. Absolutely worth it for at least one morning if there is a bunch of new.
If there is a lot of snow, there is a good chance there will be wind as well. This can suck becuase it will close some chairs like Peak, Harmony/Symphony and 7th Heaven. However, these chairs will sometimes opne late so if you stay of top of things, you can get the goods while others don't realize it has opened.
If Peak chair is open, hit all the stuff lookers right of the chair when looking at the trail map. You wrap around on the backside of the mountain and then there is a bunch of stuff that funnels back down to the bottom.
The whole Harmony/Symphony area is pretty sweet, but it's been closed the last few times I've had good snow because of wind.
If you like trees, a pretty fun area that doesn't get tracked as bad is off the Crystal chair (far left of the trail map for Blackcomb). The only thing that sucks is that you get funneled down to Excelerator Express which gets a huge line and you have to take two chairs to get back to the top of Crystal. The positive is that we were still getting some fresh tracks in the afternoon when the rest of the mountain was toast.
