On the Hilleberg Tarra/Savio, are the poles on the inside of the flysheet or outside or both?? it's quite hard to tell from the photo's provided as i can see poles on both!!! Os there just one set of poles or is it double strengthend?
The poles are external on both. There are short sleeves at the bases which the ends of the poles go into and then you clip the rest of the outer to the poles. It's very, very quick and easy, far easier than other geodesics I've used. If you follow the links to the Pitching Instructions or look in their general Tent Handbook you'll see diagrams of how it works.
There is also a cover that goes over the top of the tent to keep the chimney vents out of the elements. It just clips on with toggles and rings.
The inner usually lives clipped to the outer, so both go up at once, though you can unclip the inner if you want.
There is one set of 4 poles as standard but the tent is designed to take double poling if you want. Just buy an extra set, the short sleeves are wide enough for both sets and you clip every othger clip to alternate poles.
I have a Tarra, and if you want a geodesic at that size I think it has a lot to recommend it. It's fearsomely expensive, but I think you do get something for your money. The porches are a good size, it's not excessivley heavy, the ventilation is very good (thanks to the chimney vents in the roof), it's well and away the easiest tent in its class to put up I've ever seen and the materials and workmanship are as good as anything you'll find.
Here's my OM review of it
If it was abducted by aliens I'd probably get another, though possibly a Staika dome (cheaper, a little lighter, a little less inner space and slightly smaller porches, but no need to peg out the porches and still bombproof), or maybe a Saivo.
The Cruxes look very good too, but personally I much prefer a tent that goes up all in one rather than bugger about with separate inner first. The Hillebergs are just much easier tents to pitch IME. I also like a porch at each end, but that's just personal preference than an objective better/worse thing.
This is yet another case of a failed Terra Nova pole on top of the three folk I know personally it's happened more than once to on their Quasars. Not good!
