I do have a Trangia and a popcan stove. I never found myself using them too often for some reason. I tend to gravitate to my SuperFly more often than not. I may just bite the bullet and get a multi-fuel.
Also, I am really leaning toward a NEMO Obi Elite 1P tent, the NEMO Siren 30 quilt, and an ExPed SynMat 7 UL for a shelter/sleep system. Anybody think any of this is a bad idea for 3-season backpacking? All together they weigh 4 lbs and 9 oz or something. That's pretty light for some decent luxury in my opinion.
