I should clarify, For the colored Pitt pens that is I want more nib variety. They have a wide variety of nibs in black, gray, and sepia last I checked. I agree with you on the Pitt assessment, I never really got a good hold on Microns even though they are the ones usually recommended and I have a few, I tend to get a lot of skipping with Microns, but I like the way Pitt pens feel in my hand and the ink just slides out so smooth. Truth though many of my Microns are old, so are my Pitts and I Don't have any issues with them till the ink starts to run out.
