Another rare poster here, Sorry- I just can't keep up with how fast the threads move
And I am shocked that anyone would bother to troll a thread like these, just pathetic!
I tend to post when I need advice
which I would like to currently know about double clarinet cases please truffle if it's a travel-type case? We have a good hard double case (briefcase style I mean) but it's a hassle for DD carrying (and I'm always petrified she'll leave on a bus somewhere).
Anyway, I have DD, 13, now attends a junior Department, plays piano, clarinet, percussion, and sings, and DS, 10, plays piano, clarinet, percussion, and doesn't sing, and definitely doesn't want to do JD! 
Them doing the same instruments was down to their own choices, not my choice, but in fact it works well for us, and cuts down the amount we have to spend on sheet music etc. Also makes going to teachers easier, as they have had consecutive lessons etc. That's even easier now most lessons happen at JD or at school.
I'll just wave at the thread from time to time...
