Hello Everyone, first post for me....been trolling and know this is a topic that has been discussed before...but wanted to dust off and see if any new developments/learnings are out there to share.. just purchased a le grande rollerball...love the pen and love the rollerballs (more practical for daily work use than my le grand fp).....but don't love the lifespan of the rollerball refills....looking for alternatives... seen refilling the MB cartridge hacks....i'm more inclined to using a G2 refill (decent writer, much better lifespan, more color choices), but have not found a good way to make it fit into the le grande..... any recent hacks/innovations in this sphere? PS: i've seen the reverse hack online, trying to use a MB rollerball cartridge in a G2....dont understand this, since this is essentially a value play and the MB rollerball does not provide as much value as the G2 cartridges....
