The Diplomat Aero is a great pen for daily use. It feels very natural in the hand and I find that I look for reasons to write with it just because it's such an enjoyable experience. The nib glides more smoothly with Lamy ink than it does with Diplomat ink, but this is almost certainly going to be a matter of personal preference for each user. The nib is one of the smoothest writing steel nibs I've experienced, but I almost wish I had chosen the gold nib. Still, I instinctively reach for the Diplomat Aero far more than my Lamy Safari (which I don't really like at all) and the beautifully handcrafted pen I received as a Christmas gift.
