The Fusion is a great dry suit if you intend to dive in a variety of water temperatures. I have the Sport skin on one of mine, and it is light and packs into a surprisingly small space. I put the user-replaceable seal system on it, so if I travel, I can replace a seal in the field and not lose more than one dive. The big downside of the Sport skin is not having pockets. I have the Tech skin on my other suit, which has pockets, although they aren't ideal ones. The Tech skin is heavier and takes longer to dry. I suppose it protects the suit a bit more, but the combination of the Sport skin and the inner bag is awfully hard to hurt. I didn't like the Bullet skin at all, because it was heavier, less flexible, and a PITA to deal with.
