For note taking with a fountain pen, which I do, there is no better paper than Maruman Mnemosyne.
While there is a lot of variety in ink, and I like to swap between several colors and pens, Maruman Mnemosyne is the most reliable paper I've found to write upon with my fountain pens. It takes a lot of ink to bleed through, doesn't feather very much, and allows my nibs to glide over the paper.
I like quad-ruled paper, as well. Makes it easier for me to sketch things, or to organize the page. College-ruled paper annoys me.
Mnemosyne was the Greek goddess of memory and gave birth to the muses. "Nemo" is right there in the middle. He's my dog.
