The far side of the mountain has the best runs. Like p-hat said, Gunnar lift, which is a high speed man lift gives you teh best runs with long black diamond runs. It also gives you the "glades" which turn into moguls pretty quickly and I suggest you avoid unless there is a lot of fresh snow. Bad thinkg about the Gunnar lift is that it closes at 4:30.
After Gunnar closes, I always head over to the North Face lifts. These lifts are pretty slow, but they give you my favortie run, North Face, and my 2 favorite parks in The Alley and North Park. They alley is mainly jibs, but it does have 3 small jumps and 2 medium jumps also. North Park has a 10 or 13 foot halfpipe which is always fun and some pretty big jumps.
If you are into the huge jumps and parks, then the Spot is where you want to be. They have a pipe with 18 foot walls and a couple 40-50 foot jumps.
