I have an atty question, so this might seem like an odd place to post this, but there's a method to my madness. I'm a carto guy because I like the low maintenance involved. Especially with a home made carto tank. But for diy, cartos are such a pain to clean out for slight changes. So...
Anyone out there who pretty much just uses attys for flavor testing? If so, do you have a recommendation for a good user-friendly atty for a 501?

I use both so I really have no preference, but it is easy peasy to change a carto (especially one that has a flavor stuck in the filler) into a tester.
