Balanced Construction of Engineered Hardwood

You've all probably heard about unbalanced construction of hardwood flooring ie; too thick of a surface veneer as compared to the sub ply construction.

For years it seem to be a competition of manufactures to get more sub plys under the surface plys theoretically make the product more stable. There are three ply to nine plys out there.

New supposed theory's and tests seem to confirm that too thick a veneer is much like having a solid glued to plywood according to the "experts". I seriously doubt this and have never yet seen any problem of which these hardwood experts claim is going on, least in my zone. To think a 3/16 in or even a 1/14 in veneer is going to act like a 3/4 inch solid seems ludicrous to me, unless the sub-plys are some really ridiculously unstable wood other than whats on top.

I am just wondering if it is such a problem when are the manufactures going to jump on this bandwagon as I have yet to see thicker balanced sub plys matching the thicker surface veneers. I still dont see any matching sub plys yet.
