#OnePenOneDay Rotring Tikky Ballpoint

The Rotring Tikky Ballpoint has one of my favorite pen barrels, but its traditional 1.0mm ballpoint is just average. I switched out the refill a long time ago with a black Parker Gel 0.7mm, and while it is better than the original ballpoint, it still isn't great. It drags across the page much more than you would expect from that size of refill. I'm still on the hunt.
