In response to regulator adjustments for cold water.

The first stage regulator should always be adjust to the optimal design 
specifications.  The second stage is usually detuned (set below optimal 
design spefications) to decrease the possiblity of regulator free flows 
that often result in regulator freezing.  The best way to "Properly" set 
the regulator is to tune it to factory settings and then slightly back 
off the second stage adjustment.  This does not significantly affect 
breathing effort, but does decrease regulator freezing.

You did not mention the type of regulator you use, however, the type of 
anti-freeze protection (environmental protection) used in regulators will 
influence the type of maintenace you do for cold water diving.  If you 
dive a silicon protected regulator and experience an extended free flow or 
freeze, you should totally disassemble and clean the 1st stage.  When the 
regulator freezes moisture is drawn to the piston surface were it 
freeze.  When the regulator thaws the moisture is trapped against the 
piston and will refreeze with your next use.
