If you are asking me, then you will have to excuse me for laughing - the
hose diameter at the IP is insignificant . The diameter to flow fromulas
are for one ATA, not consntlhy prssuized hoses fed by a reductiuon
regulator. The 1/2 inch hose is a boat monkey dive industry bullshit
story to sell to the uninitiated neophyt.

It might sound real good and logical to the Force Fin mentiality of the
dive insduetry and appeal to the savants who teadh diving, but the fact
is you can start jet engine through a 3/8 hose, and the fucking fittings
are smaller anyway, as is the orifice in the reg and on the tank. Give
me a break. 

Odd size hoses are a screw job to all of us, and have nothing to do with
breathing.

Adding "lead rings" - come on, this is just too much. Anytime you have
to do something like this, something is wrong.
