Dear all, I recently bought myself yet another Platinum Preppy (in 03 = fine) in red. Naturally it came with one red cartridge. I can't say that I was all that convinced by that ink; it was pinkish, did not flow so well (didn't even saturate the fins of the feed properly), and it would dry up at times) So now I'm looking for a better ink for that pen; still red and just for grading papers. So, I'd like an ink that's - a more true red, - not pale, - behaving well on all kinds of sub-par paper, - not easy to dry up (since the preppy is what it ts), - price and size of bottle should not be too great. - Can't be Noodler's; not available here. I've considered Sheaffer Skrip Red, and Diamine Wild Strawberry so far. If you have other suggestions, please share your ideas. Thanks a bunch. Edit: I live in a very humid environment, so I was worried about the Sheaffer's distinct lack of water resistance. The humidity here definitely affects paper over time, and when left out in the open.
