For a while now I have been looking at options to replace my wife's sleeping bag (a marmot trestle that weighs 4 1/2 lbs or so). We tend to zip our sleeping bags together often, so I started looking into options for couples. I looked at some double bags but many were too expensive, ie feathered friends spoonbill, or too heavy, ie big agnes king solomon. Anyone have experience using backpacking quilts for couples?

In particular I like how the enlightened equipment revelation looks. The XWIDE is 64", which is wider than most I've seen, but it seems like it might be just barely too narrow. We are both pretty small people, I'm 5' 9" and she is 5' 2" but I was still slightly concerned about it. Anyone have experience with similarly sized quilts, or maybe semi-rectangular bags (I think Western Mountaineering's semi-rectangulars are 64"). In particular I was hoping someone would have experience using a quilt for couples down to 20 degrees. Any information or suggestions are much appreciated!
