I've owned the zippered gastank for a while and earlier this year bought the biggest flip top Tailfin one. Much as I like my Revelate gear, there's no competition - the Tailfin is absolutely rock solid without anything round the steerer due to the V-mounts on the underside. Welded seams so it's completely rainproof and the magnetic catch means it's super easy to get stuff in and out one-handed, while riding along. I also have one of their downtube bags for spares, same mounting system and it's great.
I've lent the Gastank to a friend but I won't be asking for it back anytime soon!
