The Multiball lays down a pretty fine line, but the ink flow is good which makes for dark, solid lettering on the page. The writing experience isn't smooth by any means and there is a considerable amount of drag on the page. I thought it might just be my Doane Paper as it is a pretty heavy stock and not overly smooth, but when I went to a Rhodia 5x5 Block pad, the experience was a bit better but not by much.
The grip on the pen is actually very good. It has just enough flex and enough rubbery feel to be really effective. Never during my time of writing did I feel like my grip on the barrel slipped.
I think I might have a love/hate with this pen. There are times I really don't like it, but when I feel like I get into a good handwriting "groove", the words on the page are neat, dark, and precise which I like. I would not recommend this pen as an everyday writer if smooth is your thing.
