[Quiet Man Cometh]

Well...that's my learning for the day. I didn't know there was a distinction between ballpoint and rollerball pens.

Looking it up, the Zebra Z-Grip Flight is a ballpoint. I had a rollerball pen (Uni-Ball Vision) and loved it right up until I took it on a plane and the cabin pressure caused the ink to push out the pen nib and visibly drip on my paper. It's been bleeding slightly ever since. I do not advise taking any liquidy pen on a plane if you want to preserve it.
