As I said in the past, a perfect ultra light solution never exists for all conditions. I agree totally with Roger. He has *two* tents that are most often used when he is with his partner. They appear to be similar, but the engineering and practical construction details behind using two different tents sort'a precludes using a single tent with a detachable inner liner. This can also be problem when presented to anyone in terms of comercialization. I am afraid that much of the basic design will be lost if it does go comercial. Production is not ammenable to a lot of the details that Roger presents. That said, I wish it were possible.
Typically, cottage gear is a very tiny market for those who simply want the best thay can get in some category. Example: In some cases weight is a super high criteria. You live, eat and breath weight. An 8oz pack is simply too heavy. In the cottage market, you can find a pack for 3oz, with accessories, 5oz. the 3oz weight savings is the driving factor.
In that same market, durability is important. There are a few people (like me) that continue to use the venerable and somewhat heavier SVEA 123. It works and has worked for the past 40 years or so. No maintenence and highly efficient. Others, like Roger, place a value on extreme conditions. High winds, heavy rains, etc. Warm and dry at night is about all you can ask for. It works. As said, I like my Exped Sirius for really tough going. But, it doesn't have a place in a 10lb pack at almost 6lbs. It is NOT for solo use. 2#8, I would consider, but even that's a heck of lot.
So, as much as we would like to have Rogers tents out there and available, I sort'a doubt there will be any takers from the big named companies. The niche market says it will never sell as well as other tents with bigger names. He will probably need to do it all himself for slave wages reinvested till he can make the large dollar volume purchases that drive costs down. He will be competing with old and well established firms, Hilleberg in particular, on weight, mostly. Roger needs a gimmick, that he can patent, to make it work. Better vents, better poles, etc...besides the higher quality of craftsman production. Like I say, a hard sell.
From engineering tubular designs (I build UL canoes,) I know how difficult it is to translate a seemingly perfect design into a practical expresion of your paper concept. As Roger points out, he has had many iterations on the same theme. As a MYOG project, these are great. Without the tooling to make the poles, without the correct size of tubing (a few thousands in an arrow shaft make little difference,)without the correct inner canopy materials sought out and purchased, without a ready supply of labour, this can be a problem for most of us.
Anyway, just some thoughts...
