Quick pen question

[Deuce]

I have a quick question, I recently picked up two of the Retro 51 pens after reading through a couple of the "Pen" threads here (You guys make me spend way too much money... )
I love the look, I love the feel. Problem is, I don't love how it writes. It's ok, but not great. Does anyone know what size the tip is? 0.7mm? I'd like to try to find a refill that puts out a bit more ink, or has a larger tip, or a smaller tip.. just a refill that would fit in the pen and writes differently. Anyone out here know of a refill that I might have better luck with? I'm afraid I don't even know where to look for this kind of info. If it makes a difference they are both in the "Tornado" lineup.

Thanks!

Check for regular ink (liquid) refills vs gelled ink refills. I don't know what genius decided to put those out, but the gel ink cartridges absolutely suck, IMO.

Go to http://www.levenger.com/

Shipping is free on all their ink refills, they have a ton of different types, and usually they show measurements somewhere on the page so you can compare it to what came out of your pen and make sure it fits. GREAT customer service.
