   For a medium-bounce gymnastics floor, 4" blocks of foam (don't know the density but could find out probably) are glued to 1/2 ply. Then other sheets of 1/2 ply are staggered over this and screwed. Now, we cover this with 2" thick rolls of a spongy foam (kinda like wrestling mats) and covered with carpet. But it might work to nail the bamboo to the ply.

   thanks--I think I'm understanding what you're describing.......but I'm dealing with a NYC apartment where I realistically can't raise the floor more than 1 1/2" to 2" from subfloor to finished floor.  I guess I'm looking for a quick way to give him a floor with more give than a floor laid on 3/4" plywood sleepers.  there's no real protocol for what I'm trying to do unfortunately.

   thanks for responding.

   Why dont you try two layers of 1/2 " plywood with 3/8" sport pads under the bottom layer for your subfloor

   Wait a minute, these guys break bricks with their bare hands and concrete blocks with their ear lobes and he wants a springy bambo floor?  Another dojo wimp, if you ask me {VBG}

   Perhaps you'd be the most appropriate one to go there and explain this in person to him. <G>

   Ahh, yes, Grasshopper.  Notice that I said "If you ask me."  Fortunately, nobody asked me, so hypothetical it is <G>

   Try looking into a "portable" dance floor - Harlequin Floors. They sell roll-up floors that would appear to be what you need - 3/8" foam sandwich amoungst other offerings. Another idea would be to visit a well established karate school and see what type of floor they practice on.

   At a local Tae Kwan Do school they told me their bamboo floor (very nice) floated over a carpet underpad to take some of the jolt out of the floor..

   What you are looking for is overall resilience, not greater deflection between sleepers.

   You have two possibilities - one is to use the high-density resilient blocks from a company called Stage Step (800) 523-0961, the other is to use Miller bridge bearing neoprene blocks.  There are lots of other considerations too, like using FG insul between the sleepers to overcome that hollow feeling.
