Thanks for offering to check out the quilts, but that won't be necessary - we can hang them a bit looser and mess with the suspension and make them work. Lots of folks hung UQ's without differential baffles for a long time, so we will figure it out.
The difference in our observations is probably because the Clark is symmetrical and the WBBB is asym, so my weight is way to the left of the quilt while you were probably more in the center. I've already got a couple ideas about how to hang the UQ to both match the asym lay of the hammock better and to avoid compressing the down. I'm confident we'll make it work.
