Thread is about pack weight, not glissade technique; saving that discussion for a different thread will keep this one more helpful to people interested in the original subject.
In response to the pertinent replies above:
 Will definitely bring a warmer insulating jacket and a warmer bag. Thanks!
 Glove progression is barehanded, shells only, shells & liners. If the temperature is right for a light liner, I find it is warm enough for skin or cool enough for shells.
 A couple people have said to ditch the waterproof pants. I'm wearing thin, unlined soft shell pants— Simple Guides. Long underwear is not convenient to take on and off as conditions warrant. Shell pants and belay pants are, hence the "rain pants" on the list. I think the terminology was confusing.
 Sit pad— do you find that sitting rests allows you to move faster than you would if you left the foam pad at home? I'll have to consider that.
 Yes, the repair kit is a knife, duct tape, band-aids, Tums. No sunglass case— I wrap them in layers. I carry crampons in the pack.
 OK, we'll ditch the shovel and bring a snowclaw, since it makes a nice frame for my pack.
 Again on the "rain pants," these aren't for rain (that's why we aren't bringing a waterproof tent) but for cold, wind, and glissading. They are the 2nd piece of clothing on my legs (besides boxers).
 I think that's all! Thanks. Looks like the sit pad is still in question. I'll try it and see if I move faster.
How about Kahtoola crampons, vs. Neves or Air Techs? There's a half pound one could save.
