Guess you found your happy carry case then, no?
I really love this carrying case to be honest, it can be thrown in a backpack and will resist my turbulent daily usage without complaints.
The best usage for this case so far has been placing IEMs together with silica bags in it so all IEMs stay nice and dry - especially their drivers.
I think I'd use it more like how you are, I don't really take my AP60 anywhere. I'll probably spring for a Pelican i1010 or something.
