Which brings up an interesting point about downbearing generally as it relates to RC&S designs. Since the board is designed to have the required amount of stiffness without compression and without that added compression afforded by downbearing, how much downbearing is appropriate for these boards. I say very little is required and my experience (and experiments) would seem to suggest that. In fact, normal downbearing settings might even be detrimental and inhibit the board's up and down movement. I've come to the conclusion that on true RC&S designs only about .5 degree of bearing is required in the mid tenor, about .5 - .75 through the treble. As is typical of other designs, 0 - .5 degrees of bearing in the bass. It seems to be much easier to overload these boards than to underload them and traditional bearing settings don't seem to bring out the best results.
