Hit the T bar on Blackcomb, climb the glacier, see the ice cave. It's a wide open bowl so you can traverse it back and fourth if it's a bit steep for you. As others have noted, Peak to Creek run if the peak chair is open, on the same side, Dave Murray downhill is silly fun.
If you get blasted with snow, the Blackcomb side will usually open first, it's runs are mostly a little steeper and narrower, which is fine on a powder day. The whistler side has the Peak chair which is super fun to simply watch at when they open the top of the mountain if it's been closed. You get to watch some serious cliff drops and really awesome skiing while waiting. The Whistler side feels wider and less steep than Blackcomb overall.
