Steve - I believe you are wrong. I don't have the formula handy for
calculating tensile strength of a round member, but diameter is the
single-most important factor, as it is exponential, not linear. I have
the formula at home somewhere, and can dig it out, if there is interest,
and nobody else has it handy... 73 Barry
