I got one a couple weeks ago for my JRB Bridge hammock. Together they are a sleepers dream. However,
Yes the stuff sack inflation system is very bad. Don't know how long it took me to get that thing full but I was cursing it. Did it once and never again. What I did was use my pillow pump from exped. I take the pillow with me anyway and it filled that sucker in no time. Just go to your local hardware store and buy some plastic tubing. I used some I had laying around for my fish tanks. Boil some water, stick the tubing ends in for a while and spread the openings with something until it matches the fittings on the exped pillow pump and all season pad.
Regarding noise, yes at first it sounded like you were in a Christmas present filled with all that tissue wrap. Its gone down some with use and in my hammock I dont even really hearit at all, but definitely still there when using on the ground. Ive also got the xped ul 7 and much prefer the all season. Probably sell that one sometime soon.
