I know we've discussed before how vastly different our naming styles are, but here is what I do like/love* from your first list:
Opal -Okay, I actually don't like this, but it's so similiar to Mabel that I wonder how you can like it but call Mabel a "servant name. Or old, obese chain-smoking gum-snapping greasy-spoon waitress." Surely that image is brought to mind with Opal as well then.
Phillip -Sometimes I like Phillip and sometimes I don't and I don't know why, but today it's okay. Not excited about it, but it's okay.
