I use Private Reserve DC Supershow Blue as my go-to blue ink. I haven't had any problems with it, and since I don't take very comprehensive notes ink often sits in my pens for months. The DCSS is a great color; it displays lots of beautiful tones of blue so that it manages to be vibrant without being visually fatiguing.
As for Noodlers, I've tried Eel Green and Tiananmen Red. Neither of these inks have given me problems either. I don't use the red in piston fillers or demonstrators since red ink generally stains, but I have used the Eel green and had no staining issues. Furthermore, the green did not strike me as particularly dry (especially compared to Pelikan/Cross ink). I use it in my Montblanc 149 because I can't take the pen apart to apply silicon grease like I can with my Pelikans or Pilot Custom 823.
