appearance and design -- love the colors available. wish there was a solid black, or even a dark green/black swirl. that would be awesome. i don't like the little steps at either end of the pen too much for aesthetic reasons. looks kind of goofy. also think the clip is kinda funny lookin, but it's a very nice functional clip. very easy to grab when slipping it in a pocket.
build quality -- very good. only bad thing is the feed may come loose when flushing it out. at least it did for me. maybe i was a bit overzealous and pumping a little too fast. because of this I've taken the converter off and I'm using it as an eyedropper. So far so good. Really like that converter. I'm definitely going to get a new o-ring for it. Maybe I'll cut the one I have to put a nice little groove in it.
clip is sturdy and works great. cap ring rotates when i fiddle with it - but not really that big of a deal.
size -- big and light weight. love it. much better in my hand than the earlier flex pens.
nib -- was quite toothy at first, but after a turn on my polishing wheel it's very nice and smooth. good line variation as well. i don't feel like I have to push really hard to get a fat line.
flow - after a very good cleaning with some 409 and running an xacto down the channel to be sure it was clear of any debris, it's perfect. only with very fast flexing and drawing do i get any railroading. only twice on the drawing below did it do this. never skipped once. using Noodler's Heart of Darkness.
Why the heart? Well, the heart has been on my mind b/c of an art contest that some of my students have been participating in and it sort of just popped up on the page after I drew the first center arrow. Why the arrows? Stole them from one of my kids who is always coming up with really cool designs based around arrows. First time she saw one of my worm drawings with arrows, she said "You stole it!" I love being inspired by my students.
Edit to add: both pages are 8.5 by 11 inch HP 32 lb copy paper. Good stuff.
