#19 is good but needs to be a little more readable and crisp. I could see a bit more color and also without the gradient. #17 I like better if the "line" design element wasnt there. I do however like the font and would love to see this on a solid white/black backround.
I love the font in # 164, I would however like to see it in the color palette of what we have in RANK #1 right now. I think that it would add that certain soft quality that we are looking for!
