Well, I'm not sure that I "really love" a 5 on tenor, as opposed to a 6. It's just the one I've been using, and haven't tried a 6 in a while, and I think a little more open might be a good thing for me for tenor (slightly less restrictive, perhaps). Either way though, it seems like the c-mel being slightly smaller that using a 5 on it might be like using a 6 on tenor. Since you use a 6 on both maybe it would be smart for me to start with a 5....Anyway, I'll let you know what I think of the Aquilasax when I get to play it. Thanks again!
