Big White doesnt have excessive steeps and cliffs so your gonna have to go lookin and asking around. I'll give you a few ideas of places to look for the best skiing.
Bullet chair - Skiers left at top of the chair, follow the ridgline down and up into the tree's around the ridge, nice steep chutes with powdery tree skiing below it. the sections called easter chutes and is the best runs on the bullet.
T-Bar - Skiers left at the top go check out the cliff, big wide open bowl, few big skiable chutes just up the ridge and if you hike to the top of the far peak (east peak) i've heard its really fun. Skiers right go as far right as you can to reach the area that leads into the Falcon Chair, lots of steeps in there and a few cliff bands. If your lucky enough to have the falcon chair open, you can see tons of sweet stuff from there.
Powder chair - go skiers right of the chair and keep following right/down until to find a long steep cliffband. tons of big size drops in there, gotta be quick as theres lots of trees aswell.
Gem Lake - go far skiers right of the chair in the out of pounds, always power, dont get lost. you can access 5 runs that are below this out of bounds by a cat track that hits eventually, these are usually closed so that means lots of pow, and unexpected drops. watch out for logs. Skiers left of the chair through the valley can lead to some big cliffs with a bit of traversing. Cliffs lead out to powder and falcon chair.
hope this will help you, if you visit all of the spots and search around them, you should be fairly happy with your trip. lots of terrain to enjoy
