I have never run across them before. After looking at the site it seems legit though. It looks as if 800 FP is going to run you 16¢ per oz. Ed Speer has down for sale at http://stores.tttrailgear.com/-strse...0fp/Detail.bok
for about 11¢ per oz of 900 FP. He appears to be out of stock right now, but if your looking for the best bang for your buck I would wait until Speer Hammocks has more in stock. Another bonus IMHO is that it comes in 3oz packages, which I would imagine would be much easier to work with than a 1lb bag. If you go with downlite, let us know how it goes.
