The SKB cases are very good. I purchased a few of them for different horns, and the SKB's fit fairly well, except for the Conn 6M. Few cases seem to fit this horn very well. The Johnson cases don't really have much room in them, that's my only complaint.

Walt Johnson are certainly the most protective for alto and tenor (the bari versions have drawbacks in protecting the upper body). Bu WJ's are also some of the most expensive. Certainly worth it if you can afford it, but you need a neck pouch to store it in the bell and theer won;t be much room for more than one mouthpiece and a couple reeds unless you buy a case cover like the Cavallero, but that's another $80 or so. For around $100, I'm a fan of the ProTec Contoured ProPac. Do not buy the rectangular as they are soft sided. The contoured version has plywood and is slightly padded outside of that - very protective and very compact with decent storeage inside for a neck and mouthpiece along with additional zipper storage on the outside for a flute or more mouthpieces, though it's not hard protected.

I had Walt put in the slots on my Bari case for extra mpc's reeds, & the neck. This was no extra charge either. I love the wheels on my Bari case. Walt has his shop not too far from me so I guess that helps in those kind of requests. He'll make whatever you want if u just ask.

I suppose the thing to do with the Walt Johnson case would be to get one of the neck bags to store the neck with the horn, and keep mouthpieces, extra reeds and accessories in a seperate briefcase. I saw a post on here a while ago, where someone was making mouthpiece cases for sale. It looked like a pretty good idea. I bought a leather briefcase to keep my mic, extra reeds, reed cutter, and accessories in, so that whatever horn I decide to play, I don't have to transfer all my gear. They are great cases, but expensive and without much room. The SKB's are a nice case for the money though, and offer more protection than the soft gig-bag style cases.
