Private Reserve inks have caused me nothing but problems:
Lake Placid Blue: skipping problems poor flow
Tanzanite: gross slime in bottle had to throw it out
Sherwood Green: rubs off paper even after it's dry
Naples Blue: rubs of paper even after it's dry
Ebony Blue: so thick it clogs pens (although washes out with water, no damage to pen) but the very opposite of "wishy washy" for sure. I recently topped off the bottle with tap water in order to thin it a bit, but haven't used it much after that so I can't tell you if the experiment improved the ink.
Diamine Midnight: this stuff gushes out of pens. If that's what you want, but there's way too much surfactant in there for it to be considered a normal and problem-free ink.
All Waterman colors: super reliable and problem free, but the green and the South Sea Blue are kind of watery looking; the brown is a nice unusual color with shading; Florida blue is a very standard blue that compares fine with the blue found in pilot roller ball pens
Shaeffer Skrip Red: recently acquired and only used in one pen, but seems pefectly fine so far, and a surprisingly saturated red for what they say is a safe and reliable ink
