Rob:

Some questions re your freezing posts:

What 1st stage(s) were used with the EXO mask?

What do you think about the "exothermic" 2nd stage with regards to 
freezing?

In regards to the poseidon Odin/Thor data, it seems that the unbalanced 1st 
stage (as found on the cyclon 300 & Thor/Oceanair) is less suceptable to 
freezing (assuming identical 2nd stages).

Is this a "real" effect (your data sets seem large enough to tell). If it 
is "real," why? My guess would be that the reduced flow of the unbalanced 
reg (~1000L/min) compared to The balanced reg (~1800 L/min) would lead to 
less gas cooling upon expansion from the tank to intermediate pressure. 

thanks, em
