Not that I dont take the point about being willing and ready to ask pertainent questions about existing proceedures mind you. But to be willing also to see that there are actually others out there in the industry who are doing just that, for example Yamaha as you mention below. As with soundboard materials, other things have been tried and were found wanting. That doesnt mean that these same materials couldnt be successfully used, but it does mean there are already a few strikes against them. Still, its good to have folks who are willing to try out new things. And not a few have wondered from time to time if the iron plate could be exchanged with something else. The darn things are heavy for one thing, and they are not as cheap as they once were. New materials are poping up all the time... who knows ?? RicB -- Richard Brekne RPT, N.P.T.F.
