Yes, it might work with regular PLA, I don't know. It was for my little lad's trick or treat night. Just couldn't get it to work - didn't try 0.2mm. This was with a Velleman Vertex and Cura / Repetier Host as the slicer. Generally prints like this work fine (e.g. Le Fab shop's elephant and mini car both work perfectly), so I'm not sure. It might be the luminous filament, it generally doesn't get the same level of finish or print as evenly as regular PLA, and like you say it is weaker as well.
