It is those corner struts and all the flat area that didn't put this tent on my list despite all its other good points

Orion wrote:Here's my little tent next to an old version of the Nallo 2 from earlier this year. It was a super windy night and the windward guyline was critical. Although my tent is not designed for snow (mesh inside) it worked well with snow piled around the edges on the windward side. My friends in the Nallo didn't sleep very well as it is prone to being noisy in the wind.

Not sure why you say that. The main pole is now 9mm, same as the Akto, and the fly now comes down to the ground. The fabric patterning is better than the Akto. And there are always the crossing poles, and stronger pitchlock corners. The only reasons to pick the Akto over the Scarp, in my opinion, are the larger vestibule and the improved stitching quality.

Hi Franco. There are several things that I couldn't quite figure out.
1. Which inner tent is assumed in the specified weight?
You just gave me that. Thank you. If it's on the Tarptent website I missed it.
2. What is the weight of the other inner(s)?
The mesh inner is about 1 oz lighter
3. The stakes
Thanks again. I found the stakes in "extras" but didn't drill down to the actual page where the weight is listed. I often take few or no stakes on trips so in my view they aren't part of the minimum weight.
4. The stuff sacks
Probably not much. But, like stakes, a stuff sack is optional.
About 3/4 oz
5. Seam sealing
I found a BPL thread just now where it was said that it should only be about 1oz, if done correctly. If all tents required this then it wouldn't matter, but some don't.
Depends on how much you dilute the silicone. higher dilution will allow you to put less , the idea is to penetrate the stitching not to coat it.
In silicone around 1 oz for the Scarp will do it . (the mineral spirit/white gas will evaporate)
6. Floor deslippification
Silnylon unfortunately has low friction with inflatable pads. When I painted the floor of our summer tent with diluted silicone it added significant weight (a few ounces). I guess I overdid it but it didn't seem like it as I was doing it. Perhaps an even higher dilution ratio was needed (I used 4:1). A decent PU coated floor might only be marginally heavier than a deslippified silnylon floor.

However, pre-bending the 7075 tubing is an art and defies common sense in a way.

Orion wrote:I don't understand your approach. Why would you treat the pre-bent radius as the maxium safe pre-bend curvature? Wouldn't it be more likely that Hilleberg was more conservative than that?
...
The front pole has 3 segments that were pre-bent and I calculated a radius of curvature of 202cm. The shorter rear pole has two curved segments with a 201cm radius of curvature, essentially the same given my crude measurements.
Compare this to the 9mm Easton poles which allow 100cm radius pre-bends.
