Finally, I was able to order what I hope is a great TQ/UQ combo for me. Sierra Designs Backcountry Quilt for my TQ, and a Enlightened Equipment 55in (to be used with a foot pad) 20° Revolt UQ. Both with treated down. I have the TQ, still waiting for for the UQ. Can't wait to get out and use them… Will give a report when I've had some hang time with them.
