I would also point out that this difference, is only found under certain conditions. Perhaps you just left out that clarifier.. but an RC board can be made stiffer then a CC board.. not if the mass and dimensions of the parts of the assembly are identical mind you, and I'm a bit doubtfull whether the RC board can get the same mass to stiffness ratio as the CC board in general. > Then again, much of the discussion seems to reflect the old "If all > you had is a hammer, everything...".

We are also blending subjective and more objective definitions of what is good and bad, what works and want doesnt to begin with. And in that lies great potential for misunderstanding and differenment. All the more reason to be pleased with the bulk of the discussion. Its been a while since such evident willingness to read closely just what the other guy is saying before replying has showed itself so clearly. I for one, am very appreciative of said concern taken. > > Bill Ballard RPT > NH Chapter, P.T.G. > Cheers RicB -- Richard Brekne RPT, N.P.T.F.
