[SML] was tempered hardboard

[Duncan Mahoney]

Our mainstage floor is topped with five-eighths inch MDF.  It's been in service for about 18 years, 6 productions a year between us and the Opera.  So far there has been no damage from casters and the damage around the traps is mostly from the gaff tape we use to seal the cracks.
