My apologies, I didn't intend to come off as dictating design.  I'm
interested in the subject and it's rare to find people knowledgeable and
willing to converse about more advanced topics.

Like many others here, I have a very significant investment in hardware to
which this directly relates.  I wanted to find out about the details of the
behavior I'm observing and the impact of various solutions as both a
business man and a student of engineering.
