I tried a different approach to cleaning these pens that were dried out since I knew I wouldn't have time over the weekend.
Rather than clean them all at once, I loaded the converters with water, pushed some through the feed, added more back, then reassembled them and let them sit. Finished cleaning them today and didn't have any trouble flushing them the rest of the way.
Less effort overall, but a lot longer time-wise.
Lamy sections are still irritating, though.
