I'm left handed and have used this site before. I have a bunch of Uni-ball Jetstream pens that I'm real happy about. I learned about those from this site in one of their previous articles. I can't tell if they're saying the Jetstream is no longer as good as it was, or these other new pens are even better, or they're just kind of pushing something new. I'm tempted to order some of the Pentel Energels, Pilot Multiball,…
The Pentel EnerGel (specifically, the "Pentel EnerGel Alloy Gel Pen - 0.7 mm - Black Ink - Silver Body") is the best pen I've ever used. It feels magically smooth with minimal smudging. For me it writes much better than the Jetstream, although if you do a ton of writing you might prefer the grip on those. I also really like the multiball (for writing on non-paper surfaces), the power tank (aka the poor man's space pen) and the Sarasa dry gel pens (less smooth than the Energel but the designs are fun)
