Okay, so I just bought a Jinhao 159 that came with a Goulet # 6 two-tone "M" nib and my plans are to use it for personal correspondence. Choices: Edelstein AVENTURINE Diamine POPPY RED Montblanc TOFFEE BROWN Waterman INTENSE BLACK I was thinking about Aventurine but a LONG letter in green sounds a bit much. OTOH, green is my favorite color and I like this one......but I STILL come back to it being overkill. Poppy Red is interesting because it is not that clownish or teacher's red, but it's STILL red. Hmmmmmmm MB toffee puts down a nice wet line and I like the color. The first pen I loaded it with had some issues, so I wonder if this may not be the way to go? W. Intense Black is another option, but black is black, right? I do have some Kon-Peki left, but a little of that goes a long way and I just emptied a pen with it. FINALLY, DA "Sherlock Holmes," but it seems pretty innocuous to me. Is the Green and/or RED too much of one thing or too little of another? Help a budding FP-lover out, will ya?
