Is this the result for pulling too hard to tension the panels?
Yes .... and no.
The pitchloc corners are diagonally opposite and have no tension adjustment for the groundsheet. You have to pull them pretty tight to get the fly nice and tight. This must stretch the groundsheet tight too. The other two corners have tension adjustment straps. It is notable that the two corners with tension adjustment are less badly damaged, so yes, likely pulling the pitchloc corners tight was part of the problem. I intend to add tension adjusters to the pitchloc corner tapes to allow the groundsheet tension to be independent of the fly tension.
But I'd also suggest that even pitched at an appropriate tension, when you get in the tent and move around, particularly if the pitch is on a slope, the groundsheet will move slightly and has the potential to pull against the straps. Or it could have been the two nights with 60mph winds?
When you say panels, note it's the sewn-in groundsheet of the inner tent we're talking about here. There are no problems with the flysheet which obviously gets pulled nice and tight.
I'd also note, to be fair to Tarptent, I'm not "complaining" here. I only notice the damage somewhere in the final 700 miles, so the tent had done 120+ nights before this happened/got big enough to notice. I just need to get this fixed, replace all the guylines (they're just worn), replace all the zip pulls, and it'll be good as new.
I've no Strat, but if the groundsheet gets too tight, would it make sense to replace the cord with shock cord to give a bit more flexibility or did I completely misunderstand this?
Good point! Elastic may well help here
X-mid has shock cord on corners on the inner.
The sil version Strats use elastic too.
Just been looking at TT's website. The SS Li must have been updated since our early 2019 version:
The pitchloc corner now appears to have an adjustable cord linking the peg to the groundsheet tape (can anyone tell what the adjuster is? Linelock?).
Good stuff, this is exactly what I was thinking about doing (maybe with some elastic involved too!)
The inner seems to have reinforcement discs in the corners, where the tensioner tape is attached (the upper one is for an elastic tape attachment which is usually attached to the fly to hold the bathtub up, not obvious in this photo)
The other update appears to be 2 way zips on the fly (not sure I'd need that).
Good on TT making continuous improvements to the design!
I repeat my earlier comment. I'd get in touch with TT about your concerns and questions. They might've already seen these and have come up with the best practises to remedy them. They might even have some fixes to send over to you.
All my Yama Mountain Gear shelters all have shock cord on the corners with mitten hooks to either clip to the stake-out points on the guy lines
or on uneven pitches wrap around the stake and back onto a bite on the elastic or back to the corner loop which the elastic is tied to.
I believe the lineloks are ladder lock type which are the same on my scarp.
Regarding the Stratospire, (and 2 person 2 trek pole shelters) . My italics.
A post by Ryan Jordan of Backpacking light.com:
"I’ve used the X-Mid 2P, the SS Sil, the SS Li, the SD High Route, the HMG Dirigo, SMD Haven, GG Two, and the Duplex.
SS Sil every time for wind. Close 2nd for the SS Li, if you pitch it properly.
The X-Mid 2P and High Route can’t be pitched tight enough (really steep walls), and the Duplex needs some more cut and sew precision.
If you need 1P, the TT Notch Sil.
Otherwise, you need more structure than what a 2-trekking pole tent can offer, or you need to hunker down in the trees.
None of these tents are awesome if winds are steady > 30 mph. Bring earplugs and use big stakes.
Interesting. He seems to have changed his mind a little since he wrote:
"The Duplex and Haven are what I’d consider “below-the-treeline” trail tents best suited for camping below the treeline in low to moderate winds. The Stratospire Li and Dirigo 2 offer the stability to push the envelope into more extreme conditions.
When comparing the Dirigo 2 to the Tarptent Stratospire Li, the most notable difference is reflected in the fabric durability. The Dirigo 2 uses a heavier weight of DCF that offers twice the Dyneema fiber density than the DCF used in the Stratospire Li. Having used shelters made with both fabrics over the years, I prefer the heavier weight DCF8 (CT2E.08) if I know I have to weather a storm like the one I encountered in the Snowy Range. Knowing that extremely high stresses are placed on fabrics and seams in high winds, the confidence that comes with more durable fabrics opens up opportunities (risks) that I may not normally take with lighter fabric weight shelters."
It's probably reassessed relative to how much better he found that the Stratospire performed in wind?
He had only had the Dirigo in 65+ mph winds...
And he had issues with the poles moving out of their grommets due to the design?
Maybe he's had more experience with the Tarptent since, and reassessed his thoughts on the fabric/build strength? Dunno.
Maybe someone needs to ask?
But I'd not think that properly pegged, a shelter with upright poles like the SS, would do worse than something with sloping poles like the Dirigo.
Going from memory, he had three problems. The problem with the grommets was due to camping on snow rather than the wind on its own; the pole sank into the snow and pushed the grommets through the material. He had used 1mm cord to extend some of the guylines and some broke while the thin cord also cut one guyline. Thirdly, the cord slipped in the linelocs.
I would say that first problem was using the tent outside its designated use, but could have been mitigated by putting something under the poles to prevent them sinking in the snow.
The second problem I suspect would happen with any tent.
The third problem can be solved by switching for better cord (as I did after someone kindly donated me some )
I think that the video that Ryan shot has been unfairly used to denigrate the Dirigo. As he says, "I used the Hyperlite Mountain Gear Dirigo 2 tent on this trip. Admittedly, this isn’t the type of conditions the tent is designed for. In fact, these conditions would be problematic for any three-season shelter." The Dirigo is not the tent for many people - quite small for 2 people, can't cook in the vestibules, rain can come in when you open the doors - but I think in wind it will do better than most.
I don't mean to suggest that the SS would do worse; his review of the Dirigo seemed to imply a kind of equivalency of the two but with the Dirigo having a stronger material, hence my post. I think the Dirigo's shape offers less hostage to the wind but the SS's pitchlocs probably add some strength. The sloping poles are connected by a cross pole and I don't think they are a weakness.
I haven't had the Dirigo in 65+mph winds, and I hope I never do. We have had it in winds predicted to be 20+mph, both end on and side on, and it didn't struggle at all. (It was certainly quieter than the Duplex.) One time we did pack up in the middle of night (it was our last night) as the noise of the wind howling over the hillside made it impossible to sleep. We have added apex guylines to ours, and use Zpacks' hooks so that both sides of the doors are secured.
What do you think is meant by "if you pitch it properly" on the SS Li? - just a get the cuben panels taut sort of thing?
Doesnt surprise me the SS comes out best.
That's what I assumed it to mean.
