For some reason, I always hesitate to use green, and then when I do, I always wonder why I don't use it more often. I find myself drawn more to the olives than to the 'grass' greens, but nonetheless, I like Lierre Sauvage.
I'll say that this ink is in the 'wet' range, with a nice flow that makes filling in spaces easy, and provides a nice writing experience. I know I'll use it for drawing, because that's mostly what I do with my fountain pens. However, if I were going to choose a green ink for writing, this is the one I'd pick.
I think I'm starting to go 'green'!
