He he... you do have a point here :) Still, I like the opposing magnets idea better. You get more stiffness by way of increased crown support and increased SB spring strength with minimal change in SB mass. And I like the tension bar that couples the rim to the belly rail. Still, I'll be interested to hear how these riblets fair over a period of 5-6 years. Cheers RicB The reasoning is probably less important than the result. If you are usingthe riblets it's because there's already a problem and the theory about what's happening with what is out the window anyway. David Love www.davidlovepianos.com
