Replacement Nozzle for FlexyDually v2

Does anyone out there have a source for a quality compatible 0.6mm nozzle to replace the one on the FlexyDually v2?

Lulzbot support recommended (with the usual caveats about how they don’t recommend changing it), but they only have up to 0.5mm nozzles there.

How important is 0.6mm? Would it drastically reduce the function if I used 0.5mm?

MatterHackers has them both in SS and Brass. Here’s a link to the brass 0.6mm nozzle

Thank you!
