I finished my Denali trip a few weeks ago, and thought I would let you know how it went.
We had great weather, the trip was short - only 16 days, but we did have 3 weather days at high camp though. After that short delay there was a window of 1 day to go to the summit, which we did; we summited 6th june. For those interested, I have a trip report on my blog; www.vanderheide.net
As far as gear and weight of gear is concerned; my personal gear, 34 pounds (excluding all food & water, fuel, tent, shovel), was 13 pounds lighter then the next lightest, and 17 pounds lighter then the heaviest in the group. I hindsight I feel I could've shaved maybe a pound or so off that, but I also would have added a few items (e.g. an extra base-layer for comfort). I never was cold or unsafe, because of my choices in gear.
When I find the time, I'll post the final gear-list here too.
