It has been my experience over the past 25 years or so that "DURON", a product of The Masonite Corporation, makes an excellent surface for working stage floors. Here at Indiana University of PA, we use a Duron surface for our main venue, and use the same material on most of our stage decks, usually on top of a layer of ½" Homasote . Duron, however, is no longer available as a product name – the best you can do is ask for 1/4” double-tempered hardboard. I would want to see a sample before I placed my order.
Our Mainspace floor, roughly 50' X 75', is heavily built on, often re-configured, and abused at least four times a year - we replaced the entire top layer three years ago, after 11 years.
