So my Noodler's Konrad Flex will be arriving soon, and I was wondering what inks, preferably darker inks, look great with the flex nib? I have both Parker Black and Blue/Black and Diamine Ancient Copper. I plan to order some better quality paper, which is my next question. What is an economical paper, preferably from gouletpens (No affiliation), that I can use for just sending some letters? Thanks for the help!!! -Franky
