I've been extremely happy with my 20 degree RevX quilt from Tim. I've been using a Big Agnes 2 person 15 degree down bag on family trips, but I've been unimpressed with the weight and warmth.
I asked Tim about the possibility of connecting two quilts for two-person use. I ended up having him make me an extra large custom 10 degree long quilt (~ 8 inches wider than his 'wide' size throughout. I use my RevX 20 degree wide on bottom, and the extra wide 10 degree long on top. I attach the two using 'slickclips' from Zimmerbuilt's hardware section. The 20 degree quilt is ~25 oz, and the custom 10 degree is about 32 oz. Both are overstuffed.
The result is that the extra wide quilt naturally tucks around the sides to attach to the narrower bottom quilt. The longer quilt on top gives you excess material to tuck around your neck and prevent drafts, since you can no longer cinch the top with two people.
For pads, I've gone with two Klymit Inertia X frame pads connected with two small pieces of two-sided velcro. With full bottom quilt coverage, the Klymit pads have been comfy into the teens.
The extra large 10 degree bag is also just the right size to cinch up tight for solo use as a fully wrapped cold weather bag.
I'm very happy how well these two quilts adapt to many different conditions.
