My EDC was a Parker Jotter...either regular or stainless, depending on my mood that day. This week, I got a Fisher SAFP5 space pen. It seems to be a nice pen...a little on the thin side for my taste, though. It came with black ink and I'm a blue ink person (mostly because I have to review and mark-up cad drawings for work and the black doesn't stand out enough) so I ordered some blue refills which should be here tomorrow. I plan to find a couple of pens that take Parker refills, put Fisher refills in them and put them in my and my wife's vehicles so we always have pens that work - no matter the temp. My wife had a fit at the price of the Fisher, even though it wasn't that expensive. If she only knew how much I've spent in Parker Jotters (pens and mechanical pencils!)
The thing that drew me to the SAFP5 was that is a solid, one-piece aluminum barrell, so I don't have to worry about breaking it when its in my back pocket. I've already had 2 different people make comments about it as it has an American flag design anodized the length of the barrell.
Time will tell if it will replace the Jotters permanently.
I think you're in for a nice surprise with those Fisher refills. I started out with a Fisher military pen, then bought a bullet space pen, and then bought a refill and put it in a retractable pen I use at work. Love never being frustrated with pens that don't work.
