I use mostly Noodler's lefties ink from Swisher's online, mostly waterproof, although I love the Noodler's turquoise which is not waterproof and not for lefties. (A problem -- checks must be waterproof. Ms. notes should also be, since they are around the most and most likely to get a drink turned over on them. So...signing cards? Keeping up my shamanic journal?)

My all time favorite is Tahitian Pearl, a blue-black Noodler's for lefties. I'd forgotten about the lubricated inks, or I would have gotten one. I still can't find my older inks! Probably in a nick-nack box by mistake.
