Agreed! 1) Love the Cross rollerball refill, though I wish it was a little thinner in line. 2) I have often diverged into other pen types - I even *shudder* have a Parker 5th.
I almost always carry 2 pens in my pocket - a FP, and a non-FP in case someone asks to borrow for a second. Nice to have a non-FP that is decent enough to lend out so people don't get upset that you gave them the "less expensive" pen in your pocket.
