>The bag I'd like to get is the Intergral Designs Renaisance, but it is $200.
For my size, that bag would weigh about 56 oz.
>43oz. Comfortable at 32, but you can easily push it to 15deg. $140.
I guess these are why I'm using a Ray-Way quilt. I made mine extra-wide and a bit longer and added an extra layer of Polarguard 3D; it only weighs 36.9 oz. It's too hot to use above +45F, and I've slept warm in it at -2F with a Micropuff (not sure the Micropuff was necessary). For summer in the Rockies, I would get the deluxe kit and either do the Alpine upgrade or wear my insulation to bed (as necessary). Cost is $65-$75. I'm not sure what it would weigh, but it would certainly be lighter than mine.
I picked up a Jacks R Better Nest down quilt (20.2 oz) for my hammock. It worked great this winter (it was my under-quilt at -2F and top-quilt at +25F, with Micropuff), and rather than making another Ray-Way quilt I'm going to use this for my 3-season top-quilt, hammock or ground. It's very nice, light, warm, sturdy and packs small. I like it.
