I have at least some of and like a lot PR: Burgundy Mist, Sherwood Green, DC Supershow Blue, and Velvet Black. I may have some others I am not thinking of. I have not had any smudging or gunking up problems.
I have a bottle of Black Velvet that I got for my wife for use with her glass dip pen and I've got a bottle of Lake Placid Blue.
I tend to associate the Lake Placid Blue with special occasions as I used it nearly two years ago to sign the registry at my wedding and I used it last year to sign the articles of incorporation for my non-profit organization.
