Your skiing experience is very interesting indeed – might make me change my mind about the skirt/chaps vs. pants question and, in this respect, I certainly agree on the pants being simpler. I also admit that the skirt/chaps combo will be easier to make, but that wouldn’t be a reason not to go with these (the fact that something is more difficult to make, wouldn’t make me decide against it).
You mentioned some other advantages of the pants (being a VB, more waterproof and the combo looking weird). First of...... I’m not at all worried about the combo being “weird” - my main concern is about my gear being functional, multi-use and as light as possible; furthermore, I want to be comfortable and safe. Whilst weight is important, I’d be willing to do concessions -as many as necessary- when it comes to comfort and safety, but certainly not because something might look “weird”.
In respect to VBL, I have no experience at all so I can’t judge this; I have read a lot about it though and it looks like people have different opinions – it has many detractors but others believe it’s great. Spending a lot of money on an item without knowing the result doesn’t appeal to me but, having said so, if I don’t try, I’ll never find out. Don’t know what to do.
With regards to pants being more waterproof: I use a very short poncho (so it doesn’t impede me seeing where to place my feet), but it’s long enough to cover myself when I would sit down whilst raining.
I’ll definitely have to give this some more thoughts but the fact that the skirt/chaps combo breathes a lot better is something that still sounds like a great advantage to me.
After your explanations about your CT2K.08 stuff sacks -thanks-, I’ll definitely save my CT2K.08 Cuben for other projects (fly of my double wall TFD Tent and a few minor items), meaning that I’ll have to buy some more (with .18 Mylar film). In your opinion, wouldn’t the HBK be a lot stronger than the K version? Having said so, if specs haven’t changed, the lightest HBK with .18 Mylar would be CT2HBK.18 (at 44.6 gr/m2), whilst the two versions Joe has (CT3.5K.18 -1.26oz- and CT5K.18 -1.43oz-) weigh 42.6 and 48.4 gr/m2. In each case we’d be talking about .18 Mylar film, but in the lighter K version the Dyneema thread inside would be 3.5K (against "only" 2 in the HBK) - in the heavier version it would even be 5K (which is supposed to be 2.5 times stronger than the 2HBK version). What I’m trying to say is that I don’t know what kind of Cuben to use for my projects: 3 Dry Bags (20 L. each) for my TFD pack 2.0, a groundsheet/tentfloor for my TFD tent and, probably, skirt/chaps + a new poncho as well (something similar to Roger’s Silnylon Mountain Poncho).
