I use a Petit1 and a Varsity daily. This one surprises everyone with its comfort for a compact pen. It even outperforms other cartridge pens - I like to refill cartridges with other inks, and while most cartridges tend to be loose after one use, these ones snap into place, preventing leaks. And both pens can be found for only $3!
Avoid Wine Red, though; it's more of a garish magenta.
