Pads are an important consideration with quilts. For instance, the EE are mostly designed for secure connection with thicker inflatables that have some structure . In my use, they don't work as well for CCF or pad setups with less structure than an inflatable (draftier). The downside is, when using an inflatable, with a quilt that is not secured to the pad they can be more drafty than on ground sleeping (air getting in underneath on movement). Pad size factors in as well. For instance drafts with quilts not secured to pads do not seem to be a big issue on big pads (my 25 inch EXPED) , but on a more narrow pad, drafts can come in from underneath more easily. The Feathered Friends flicker is sort of a nice combo , but its a little small if used like a quilt, and can be a little tight for me when used as a bag. However, it zips up secure and has a nice draft collar. I've used dual quilts on a big pad down to 0 with relative comfort, I've also gotten drafty and chilly at 35 or so depending on quilt / pad size etc.
