Did you reset the intermediate pressure when you bought the reg?  Odins come
from the factory with intermediate pressure set at about 120 psi. The
intermediate pressure is specified in the manual as 151 psi, and the first thing
you have to do when buying a new Odin is set the intermediate pressure.  The
shop where I bought the reg told me it should be readjusted after about 5 dives
and then again after another 10 or so dives while the diaphragm is initially
stressed (they did this for free, so they weren't trying to sucker me).  I have
friends who bought Odins through mail order companies, didn't know they had to
be adjusted, and had endless freeflow problems until they found out about the
intermediate pressure adjustment.
