I have a couple tablets of Strath 500 I have yet to use - I'll have to bust them out and try them. I'm a huge fan of EON boards for my comics work. I know they take inks well, but they're also wonderful for my pencils - just enough bite and the paper is super white, so I see contrast even with my initial sketch lines. It's good stuff - you can't go wrong with EON.
