I'm looking for a high quality pen. I currently have a rotring 600, twsbi ballpoint, and trcpc bolt action pen. I would like to try more high quality machined pens. I exclusively use parker iso g2 refills so that is a requirement.
I'm a fan of the Karas Kustoms Retrakt. I'm a nurse at a facility that still paper charts, so I write a ton at work. I find it to be a nice middle ground. You can get them on sale for decent prices and the weight on the aluminum version is nice.
I've got a tactile turn as well. I'd say that the details on it are nicer, it is a pricier pen, than the KK, but I find it to be too heavy for long writing sessions.
