I have a few of the Ti2 Design Techliners that use the Uni Jetstream refill. Decided to jump on a CRKT version that ships with the Space Pen refill. I just don't like that refill so I swapped with a Schmidt Easy Flow 9000. I get the occasional leakage out the nose of the refill and sometimes it stops until I remove it from the pen and put it back. I am guessing the magnets interfere with the ink? I know this was an issue with early designs and some inks. I will start trying other refills but anyone have any experience with this model yet? My bet is the Uni Jetstream version in a Parker style refill will work fine.
