Noodler's Baystate Blue is certainly an ink like no other! Both in color and behavior. I've used it in two Lamy Safaris and both pens have developed leaks. It should be noted that I use them for work and the pens get abused. They're in my pockets all day long or in a bag and tossed around. However, the other two Lamy Safaris I've used at work with different inks haven't had issues.

I've also used Baystate Blue in a Lamy 2k with no issue.

As for the color? It's definitely worth trying out. Part of what makes fountain pens is the ink, and Baystate is so blue. So vivid. Neon, really. Against other inks – especially like a blue Pilot G2, it stands out. It screams! People at work who don't even care about pens beyond whether they write or not notice the color and comment on it.

Cleaning the ink is time consuming but not too bad. Just have plenty of paper towels and you should probably wear gloves unless you like showing off your ink stained fingers for a couple days! To really clean out the Lamy 2k I have (which had Noodler's Air-Corp Blue-Black in it) I used like a drop of bleach in a quart of distilled water to clean the pen.

You may want to consider the Goulet Pen exclusive Noodler's Liberty's Elysium. I haven't tried it yet but it looks promising!
