I bought the 40# wing for much the same reasons as others. Diving in a 7 requires lots of weight for me. I will eventually move to steel tanks, and I wanted to be prepared when I do. When I worked out the math, the 40# gave me a bit of a fudge factor, while the 30# was a touch too light.
I have had my inflator replaced under the recall. I did have problems with auto-inflation with the original inflator, but the new one works like a dream. I don't use my inflator hose to deflate the wing unless I'm on the surface preparing to sink, and I've found the rear dump valve to work just dandy at dumping gas when I need or want to do so.
I haven't had a problem with the wing dumping too slow, but then I seem to be doing fairly well on my weighting so I often don't have too much air in there to begin with. My only beef is the short inflator hose, but I'm getting used to it, and it's not short if you only use it to inflate.
I love the durability of the shell.
