Yes, I looked at the Vaude Ferret, but Vaude did not want to play as they said (as far as I can remember) that they were not selling to the USA. A pity, as it is interesting.
The clips: NOT as good as a sleeve, but if there are enough of them along the length of the pole they might be functional enough. The load would be distributed, just not as well as with a sleeve. I would not want to trust them under extreme conditions without some serious testing. Safely pitching a tunnel with clips in a storm would be a little harder to do than with a sleeve imho, but I would suggest the same technique I outlined, rather than trying to put the poles over the tent and pull the clips up. The latter could easily result in grief.
Why would they use clips like this instead of a sleeve? It's easier (cheaper) to sew in a few tapes than a full sleeve. In my personal opinion they have sacrificed reliability (under extreme conditions) for price, but I am maybe biased? (Who, me???)
Perhaps I am being too harsh. Perhaps the tent is simply not intended to handle really extreme mountain conditions. Perhaps they are aiming more at a price point (about UKP400, about US$500) than at a rather small market segment. Well, fair enough, the company has to stay afloat. To be sure, it would handle milder conditions reasonably well, although I would want to check how well the seams are sealed around the tapes. Bit sad if every tape leaked through the fly! I do note they are using tape sealing, so it may be that they have looked after that problem properly. That would be nice.
How would this tent compare to the other tents at the bottom of that Vaude page? Well, again imho, it would beat all of them by a long mile. The Taurus tents would flatten in high wind. Be a bit scary. The other Power tents (Lizard and Tokee) do look like copies of some well-known American designs, don't they? OK in fine weather, but again not for high wind.
The tent does not have a lot of room inside or in the vestibule. On the other hand, it is very light, and it seems to have good ventilation. If you don't want to go any higher in price, it could be worth trying. I'd creep up on the extreme conditions carefully. In fact, I would love to test one myself.
PS: hum - this seems to have turned into a micro-review of a tent I have not touched. Ah well. Treat with caution.
