I definitely suggest the staking it out before raising it up. This gets it pretty tight all around. Getting the sides down to the ground once the center pole is up is really difficult. I like using a fixed middle stake, with a rope marked with the radius, and tighten it from the center and the sides as I go around. I have tried a few times to just set two stakes this way, and pull the sides out, but I've been hard pressed to get it symmetrical this way.
I was thinking of maybe making a pvc sleeve, at lengths between the steel post joints of the center pole
I have some pvc I put over the cross pieces before I put them up,I'm not sure if it helps, but I figured the joints there might bend, and I do hang a few light things from those poles.
I think one great feature is that it does billow, wind blows through, and under, and doesn't get too much purchase. It's in no way a dust protecting shelter. I make sure my gear is stowed wind safe, like it would be outside, before I head out. When I was listening to tarps snapping and rattling, my NPPSS was just flexing quietly. The NPPSS has a plate at the bottom of the center pole that can be nailed down. I haven't had any problems there as there is good tension from the entire structure down that pole. without that plate, I'd consider a t-post. As to the top part of the pole, in the NPPSS, there is a little plastic boot with a snap in it, with another cone of fabric sewn around that at the top of the tent. The center pole snaps up into that boot.
When it blows big, I always head home to see how things are holding up. If necessary, and if I was there in time, I think I'd just take the center pole down, collapse it and set it up again later.
As a person with limited transport space, I like the way this shelter stows away. I had a kelty tripod shelter that was even smaller, and that worked well for me too.
here's an idea I might try this year. Marine stuff is prohibitively expensive, but this idea with some heavy duty rubber tarp straps, and a rope might work for guy lines, and reduce the jolting of gusts.
