Ohh I love the Noodler's Eel series! Not too sure about the Pelikan but I'm a huge fan of the Midnight Blue and Sequoia Green. Dark Green sounds like a good choice though.
Actually, now after some thought, I am going to just get noodler's forest green, as it is much cheaper
The twsbi eco is such a good pen for the price although i have been plagued with a scratchy nib Any tips to help fix it?
Not really. I just use a thick cloth to keep the nib from corroding and try to make sure I'm not pressing too hard.
