Waterproof (Bulletproof, in Noodler's terminology) is what I'm looking for. For color, I'm looking for something close to Private Reserve American Blue. Would like to buy Noodler's if possible as they are affiliated, however loosely, with B&B, but after looking over their website I can't tell what colors, may be close. For what it's worth, I sign a lot of controlled documents at work and prefer something with a professional look to it. I have both of the B&B special inks but am looking for something else to use in the Pilot 78Gs I have on the way. One is in medium, one is in fine if it makes any difference. Any advice will be sincerely appreciated!
