First, always nice to have an Ed sighting. Hi, Ed!
Second, I'm not terribly surprised with no #5s. I doubt 5s are that popular, even if you're like I was and played a gigantic Sigurd Rascher bari 'piece. I used, what, 3.5 Vandoren Modele Jazz? Those were essentially slightly skinnier balsa wood. A 5 is probably like playing a 2x4.
Selmer's come out with a few new and interesting products over the past couple years. I'm not sure if this is some diversification strategy or they're trying to have so much debt that nobody would want to buy 'em.
