Different quilt but I have the New River with Deep Winter upgrade...a pretty bulky UQ. I found that Paul's Triangle Thingies were needed to snug it up well and now no problems. Recently did an overnighter on the upper Kern with no issues of sag. I would think that the HH "birth canal" entry will work fine with the shock corded TTs but then YMMV.
Mark is the name and If there is more than one way to understand what I just said....I meant the good one.
Earth First! We'll dirt bike ride the other planets later.
