Went with an Altus azumi. Got to try it with a B foot joint in the shop but didn't find that particularly comfortable. It's open holed as well so have to get used to that. Taking out one bung at a time I think.
Even the guy in the shop said B foot joints are really not used very often. So I stuck with the C joint and handed over the money....as well as picking up a little more sheet music.
I am enjoying the sound it produces, lovely low notes in particular.
