Chuck,
I called up Titebond to ask a few questions about the yellow glues, and
also asked about the urethane glues. They told me about an experiment
they did. They laminated up wood strips and made baseball bats using
the yellow and urethane glues. The urethane glues delaminated every
time while none of the yellow glues had that problem. I haven't trusted
the urethane glues with shock loads since then. I never tried their
experiment either.
