The difference between the information many folks here give out...and the "regurgitated" information in the "ham story" is that almost anyone here can tell you WHY it is suggested that two similar hides be used....or a smaller enclosure....or whatever.
There's nothing wrong with asking "Why???"....but it does bother me that someone (not necessarily you, but we've heard this before) suggests that we don't know what we're talking about just because the same basic guidelines are shared by so many.
