Any thoughts about what things cause the differences you observe?

Tom, how does one read the catalog specifications and somehow decided "that
one will work"? If the only way we can be certain is physical testing, then
one would wish for some way to exchange findings between the folks who have
tested and found some that work and the folks who are 'looking' for
something that will work.
