I was on the fence between the Alsek wide in 6' or 6'6" lengths. I'm a 6' toss-and-turn, side sleeper and wanted enough girth to accommodate my wide shoulders and enough length to be able to pull the quilt over my head.
I live just a few miles from the Katabatic shop - it's not set up for retail, but Aaron was accommodating and let me stop by to check out the two lengths. I decided to go with the 6'6".
As others have mentioned, the quality and workmanship are excellent - as good as it gets. No complaints with the service, either: Aaron is responsive, helpful, and friendly.
The pad attachment system is a great design - it allows for lots of flexibility to control temperature via venting or clipping down to the pad. I haven't had the chance to try it out in cold temps, yet, but suspect it will be very effective at eliminating drafts and keeping the quilt securely attached to a pad while allowing for unencumbered movement underneath the quilt.
I'll wait until I get some field experience with the quilt before posting a rated review, but my initial impressions are very favorable.
