Hi Karen,
I’ve found that with my Notch Li I need to stake out at least one guy line, usually on the side opposite my chosen door side so I’m not tripping over it.
That one guy line seems enough to tighten the catenary cut of the ridge just right.
I use standard and twisted MSR Ground Hog stakes. Twisted for the fly at each door for more hold in the ground B/C there’s more strain there.
