Hahahah dude, awesome. I had a look up those Koh-i-Noor pens, they look amazing. We can't get them here in the UK though. I've been looking for some good drawing pens. I'm doing an animation degree at the moment so we do a crap load of drawing. Totally geeking on pens dude. Hell yeah!!
my main detail pen is a Pilot. i'm a big fan of the Kooh-i-Noor 'Nexus' art pen. but they usually start leaking... i like it for a slightly thicker, more solid line. they have an amazing (***AMAZING!***) line-width control-ability. so it's really easy to feather the start, and end, of a line. i use some Sakura, Pentel, and Sharpie as well.
It's all in the detail my man. That would be awesome though, you should def do that. I'm sure there's loads of poeople who wonder who you get the lines. I'm a massive fan of how ink streams onto paper myself so I can totally relate. I only write with certain pens as I'm super fussy about how they connect with the paper what brand do you use dude?
yeah well... lol. i get o.c.d. about detail and minutia. stuff like how the ink reacts when starting and finishing a line, is a big deal to me when drawing. i've been asked so many times about that. i should take some macro photos so i can show everyone what i'm talking about.
