I found that the Zebras, while certainly attractive and satisfying in the hand, write like crap (rough feel, inconsistent ink flow). My favorite pen these days is the Pilot V5 RT, but I wish I could throw the refill for it in a body more like the Zebra 401.
I used the zebras for many years but like the smaller point on the JuiceUps and the gel seems to work better than ball point. I miss the metal body, but I would fiddle with the clip and eventually break them off.
