Thats a nice bag! I picked up a Sierra Designs Ridge Runner 15 degree down bag, in long its just under 3 pounds, way lighter than my old winter bag haha. I paid $110 from backcountry.com with discount around the holidays. I have seen a few sea to summit bags locally as well on sale.
I couldn't pass up the Sierra Design Ridgerunner 30* Long down bag for $120. 2lb5oz. That for the TQ and the Leighlo 30* 2/3 UQ my Wife got me for Christmas should keep me nice and toasty!! About the hood, I usually find a way to bunch it up and make use of it as a pillow. Why I always get a long bag though I am only 5"11"
I left my cabelas boundary waters bags in tact. I can use the bag in my HH as normal, as a TQ, and use it for camping in my popup...
Options and variety is the spice of life... and I happen to be cheap too.
The Thremarest Top Heaven is what I use. No zippers just elastic through the back. Plus it has a hood works for me. 20* down bag.
