For my son I liked the idea of washable better. Better for the environment and my wallet! But then I bought a nursing bra that came with a few samples of disposable ones and they were contoured, while my washable ones were not. MUCH more comfortable for me! I still used the washable, since I had them already, but kept an eye out for contoured ones and never found them. But that was almost 9 years ago. And I really didn't knock myself out looking. I guess it wasn't THAT important to me. Had a few other things keeping me busy :)
For my daughter, I had a friend give me almost a whole box that she had only used a few from (disposable) so I just used those. My body also regulated itself much more quickly with her, so I didn't need them as long. Just tossed a few in the diaper bag after a while just in case I went for a while between feedings. I don't remember the brand, but they were contoured. It may depend on your shape as well to see what kind fits you best.
