The ergonomics generally are not about the weight of the pen, but about how hard you must grip it to press it to the paper so friction can melt the ink when you roll the little ball across the page. You also have to write at a higher angle to keep the ball on the page. Gel pens are great. I keep my wife supplied with them, because she thinks fountain pens are too fancy. But the difference is still night and day. I let her use my Lamy 2000 once. She picked it up and started making a snarky comment, "See I don't need a fancy... Oh!" The moment it hit the page and she started writing it literally shut her up. She never made a comment about "fancy pens" again after that. We had a good laugh about it.
