(I have never installed a soundboard, or untwisted a case, but I have sure 
sat in front  Many
          
                               Howdy Ed,

        I've wondered at how one determines a case is twisted in the first 
place let alone straighten it. I've unstrung many that I thought had a 
peculiar plate flex when released from rim prison. I simply try to reinstall 
them without flex or stress.
   I far prefer a laminated hardwood case. It must have superior impedance 
qualities over say soft wood rims but can't see why they'd have any advantage 
over a laid up hard wood (maple) rim. As long as there is a firm and rigid 
foundation for plate and board to attach to then all is well in my world. 
Does this make a lick of sense?
