I have a Pelikan m200 with a custom Richard Binder nib that I love! Currently it's loaded with Private Reserve Black Magic BLue. I really, really like the color and the pen/ink combination, but I just can't get past a fair amount of nib creep. My Private Reserve inks tend to flow very heavily (thence the creep?). Is there another ink that I can get that would have a similar shade of dark purple but might not cause my creepness? I had the same problem in my Lamy Studio but when I put Waterman black in, the creep stopped. I could appreciate some help. Thanks.
