Unfortunately I can't be much help, but I can throw you this little tide bit.
At the moment CVS brand diapers are good. The new ones I bought are roomy and have yet to leak. The others I have are I guess one would call them a pull-up they are brief style and are comfortable in many ways.
I have some Rearz bambino on order, they should be here soon, as should my Rearz black seduction briefs for night use. They came very highly recommended.
So being that I am IC I'm in diapers all the time. Or at least some means of protection from bladder leaks.

The places I have been shopping are
Rearz.ca
Cuddlz shop
Adultclothdiaper.com
ABU
Littleforbig
And various other online shops. I wish someone in my state or town would have the cajones to open a AB/DL shop. That would be amazing.
A safe place for diapered folks and the young at heart can go be who they are. Be it an AB or a DL or someone exploring it or someone that's IC a place where they could feel safe and not judged.
