Flexible Filament and Layer Height

[Destroyer1727]

I was wondering if the da Vinci 1.0 pro could be used with non-xyz brand filament. If so does anyone know any good flexible filaments I could buy or if this filament would work for my printer?https://www.matterhackers.com/store/l/ninjaflex-grass-3d-printing-filament-1.75mm/sk/MKXXM66J?aff=7354 Otherwise does xyz make flexible filament for their printers? Last question, what is the lowest layer height anyone would recommend for me to go to and what is the lowest that I could go at all without it completely failing the print? Thank you.
