I was just there this past weekend.
Haywire (main/large park) is insanely good for this time of the year. The jumps are prime (15ft step down to 35ft step down to 25ft step down to 30ft step up - all rough guesses), bottom rail section is super fun, lots of options including one of the most fun features I've hit all year (triangle box...hard to explain, but super fun).
Stomping Grounds (small-medium park) was ok, didn't spend too much time there cause Haywire was so much fun. Mini Pipe was closed cause it's melting, but other than that lots of fun little jibs to play on, good for the random messing around run every now and then
Mini park is on the other side of the mountain (I don't know the name, and never went there...but heard it was 3 flat rails and 3 flat boxes)
The rest of the mountain is SUPER fun to ski as well. Take a few runs up the Timberline lift for some steeps that are tons of fun.
SuperQuad will get you to Stomping Grounds and Haywire, just get the top and go right, you'll find them.
The superpipe was fun, but didn't seem like it was cut in a while so it was a bit tricky to keep up speed and the flat bottom was full of mix snow (slow...made it even more difficult).
