Humidity has been high lately, and I've noticed on my daily carrier-Pilot Metropolitan with F nib, that on the squeeze converter, the ink sac tends to condense and sweat, like a glass of cold water in the sun. I've found that it fills up in the barrel and has to be cleaned every night, after a long day of writing. I know this can be fixed by getting a con-50 or refilling cartridges, just curious what other think. Also, I've noticed more nib creep and droplets getting in the cap, and that too has to be cleaned out daily. {I use Noodlers Blue} Has anyone else had this problem in the humidity and heat of more than usual nib creep and slightly leaking in cap? Thanks, Fitz
