I've had great luck with Durston X-mid 2. If money were no option, I'd upgrade now to the DCF version(pro).
The only downside for the 2 person version is the flat spot it takes to pitch. But I've still pitched it in some crappy places, it just wasn't pretty. The vestibule space for gear is big enough that I can fit 2p and gear under the fly.
If I only hunted solo, I'd go for the 1p. It would be easier to find places to pitch. But I'm usually with the wife or kids. The minimal weight savings going from 2p to 1p isn't worth it for me to own another tent.
I did try a DCF tarp(Hammock gear) and Bora bivy on a sheep hunt last year. It saves more weight over the tent, but it takes longer to pitch and felt less secure if the weather were to get bad. It was worth the weight savings doing 5-8 miles and 4k elevation, but for 2-3 mile elk hunts, I'll usually just do the x mid.
What kind of terrain, miles are you hiking?
If you can only choose one, I'd probably go with a tent. If you're doing crazy mileage and elevation, I'd lean towards tarp/bivy/sky ult for maximum weight savings.
You said "self-supporting," and the x-mid is a trekking pole tent, but I've tied the ridge to trees or cut sticks for tent poles many times when I didn't want to leave my trek poles. And Fizan trek poles are only ~5oz. each.
