Best bag for LD Hiking

[Almost There]

Marmot 15degree Helium...Stays warm to 15, water resistant, with a liner has kept me warm to 15 degrees, and under two pounds. It's like sleeping between two feather pillows!

Again thanks guys. You all here are by far the best group of knowledge there is anywhere. I'm looking really at one of the WM but they seem kinda flimsy to me though everyone raves about them. Also I like the Marmont Hydrogen or the Helium. Does anyone have any pro's or con's about them. I don't want to put a bunch of money in a "summer" bag because you can just use a sheet or fleece in summer. Is this a wrong approach? Yes I may wind up doing a thru or hiking most of this year somewhere. I'm planning on a sabatical or other words, "get the hell out of dodge" year.
