I think it will really help ease the line-up on Summit on pow days. Taking Hot Wheels becomes a real viable option and it should help spread everyone out quickly. Knowing you can go up to Art's and have a fun lap down to Scott (or Lakeview or Sherwood) doesn't make Summit such a no brainer anymore, and same deal for RoundHouse on windy days - you still have two pretty good options instead of a line at Roundhouse going back three towers.
There's still going to be plenty of stashes around that mountain since a lot of people refuse to hike even a little.
