Come on Jim. You don't have to like MJB, but you should at least 
respect his penetrating intellect and encyclopaedic knowledge.

In fact, we can all learn a great deal from Dr Mike. Here's some
new gems and some old pearls from his treasury of intelligent
commentary...

Black - on equipment selection...

If you're going to dive Hogarthian, the long hose (5 or 7-foot)

sense in caves, for air sharing.  
In wrecks, I have a problem with it in that the length of hose 
represents an entanglement hazard.  I prefer a 40-inch primary 
hose, and recommend bungying your long octo to your tank(s), or 
even diving with a 40-inch octo hose realizing that your buddy's 
going to have to ride your ass in an air-sharing emergency.

I think we are all privileged to witness this legend in the making.
