Replying to Best powder runs at Whistler/Blackcomb and Mount Washington?

I just bought my first pair of powder skis (2012 ARG's) and I'm going to ski for 3 days at Mount Washington and 2 days at Whistler/Blackcomb in late February.

I want to ski the the best powder runs (nothing that requires hiking preferably), with bowls, trees, pillows, cliff drops (under 40 feet). Since I am not at each mountain for a very long time, I want to know the best powder runs to ski, and make sure I get in.

Thanks.
