I recently purchased a used Lamy Dialog 3. I wrote with it before going to bed and it didn't start right up in the morning. It required a few line strokes to get it writing again. The ink that I use in it is Noodler's Heart of Darkness. My guess is, it might be the pen and ink combination that causes the problem.
What inks have you found to not have startup problems after not using it for 6 to 8 hours, a day or so?
Thanks for all your suggestions in advance.
