                     If flat sawn material is exceptable then what about the 
multi-lam. flat sawn Maple supply house blocks. I don't have any and am 
curious as to what thickness the lams. are.
       I would think using this material would be labor saver and an 
economical alternative even if not as optimal as the quarter sawn variety you 
currently are manufacturing. Also with stock that thin (2mm) it tends to 
split up in the planer when it hits grain that's running out towards the 
surface. Do you find this?
        Tonally speaking do you find any observable aural (though probably 
subjective) enhancement or deficit? I'm only looking for an opinion here. 
Certainly the lack of false beats and the hardness around the top of the pin 
should contribute to a very effiecent energy transmission resulting in a 
solid tone. Oh yes and of course bridge integrity and longevity a big plus in 
my book.
