Sorry for not answering, but I HATE the looading time of this site these days!
As for tents, well, do what you like. I have spent closer to a year on 79 degrees north, and spent more than 100 tent nights in the scandinavian arctic. I for one would not choose ventile over synthetics for a trip going on skiis or anything musclepowered (dogs etc.). Cooking is not a problem in a good tent, no matter what material.
IMHO ventile has it's pros, no material is really any better than any other, just suitable to different things. Ventile is perfect for activities which include fires and stalking, such as hunting and wilderness living, where rain isn't a huge factor. Also good for clothing for cold and dry environments (antarctica, the arctic) but without a lot of mechanical abrasion (mountains put a real strain on ventile). For tents, I beleive, in conjuction with most manufacturers, distributors, vendors, end-users, that there are better alternatives to ventile.
So, let's go have a beer, to celebrate tengus new tent instead!
