Jim,

Nope, plain and simple crush. The softer panel can't "push back" hard enough
during summer swelling to balance the pressure the denser panel produces, so
it crushes. It'll be the first to crack in winter dryness as a result. It's
a "weak link in a chain" sort of thing. 

PS: My "Central West Region Idiom and Colloquialism Guide and Doorstop"
doesn't seem to make mention of the word "pooch", except in passing as a
reference to "bow-wow" level PSOs. Is there a new edition out with new
additions? <G>
