    Donna, I'll have to go with you.  In my presentation this year at the
    Santa Fe Symposium what your saying is one of my main topics for
    reducing defects in production casting.  For production models I
    highly recommend nickel silver models and gold solder.  The reaction
    that sterling models have to the sulfur in the natural rubber molds
    cause all kinds of production defects as more and more molds are
    made.  The silver solder pits, the silver surface gets rougher and
    rougher, and the typical production mold cutter doesn't stop to clean
    them up.  Even if they did, it would actually make matters worse
    because of the change in configuration of the models over time. 
    Don't you ever change and please could you forward your sources of
    nickel silver sheet and wire to the rest of the orchid community. 
    You should start a movement.
