Or you can maintain the traditional panel approach, but you can make different sections out of different woods (finger joints in the individual flitches). You can change grain angles also mid-panel if you wish. Del talked in his Dallas design class about optimal grain angles on soundboard panels - but optimal for treble will necessitate a compromise in the bass - and vice versa. Why not make the panel with two or more grain angles - it would not be very difficult?
