Ron Yes I see. My point was that if the board was set up to be a spring it would require bearing to make it work. Many boards that were initially designed to be compressed by bearing & then went flat (Or near zero) will with adequate bearing still sound pretty dang good. Obviously the mass & stiffness inherent in these flattened systems was substantial enough to make them work but they are the exception in MO not the rule. Dale And I was, of course, talking about something designed and built for zero bearing and zero crown throughout, not something that was designed for positive bearing and crown and badly built.
