Apologies if this has been asked elsewhere. If it has, I won't be offended by a cursory link in that direction. My Pilot 78g has spent the last few months confined to a drawer after becoming scratchy and rubbish. I'd been using a Con 50 and had tried a variety of inks. Despite it being my cheapest pen by a good £10 I missed it dearly so I popped one of the proprietary black cartridges in last night and, lo and behold, it's smooth and beautiful again. I promptly ordered a pack of red Pilot cartridges and am looking forward to bringing it into my marking rotation*. So my question is this: has this happened to anyone else? Unrelated: I'm waiting for Bronze Lizard MR (Metropolitan to you guys) that will be used with Diamine Imperial Purple cartridges. Quite excited. *I divide the number of items I have to mark by the number of pens currently holding ink on the broadly red spectrum (runs from Magenta - Oxblood via Ancient Copper) and keep myself motivated with the promise of a new colour every X books/papers. Is this nerdy? I don't care...
