Which pen should I choose?

You know I had to go there. Here are a few of the pens I am considering for my one pen-ink-journal challenge. Although I like high-capacity demonstrators with medium nibs, I am open to other pens. I also feel like I should use my gold nib pens more often. Neglected pens are unhappy pens! Which of these pens would you prefer? Or if you had to pick only one of your own pens, which one would it be? All suggestions are greatly appreciated!
