It will be then like an overkill to convert them in too Deco regulator in the case I put my hands on APEKS mains, am I better off staying with them as my mains since they are as well balanced?
My comment comes that, I don't like how the unbalanced regulators breath, is there a technical reason why they should be piston unbalanced ?

Didn't know that, I was under the wrong impression that it was the lubricants and the seals that were not compatible with high O2, so they have to be a dedicated Nitrox only regulator, does this means higher than 40% O2 use only.
Don't understand exactly were you will contaminate the O2 regulator, to where it can be dangerus if you use it with air, are there concerns of auto ignition ? In a small volume area trapped from the 1st to the 2nd stage, by the purging test when you install them on the O2 bottle, will it not eliminate whatever makes it not clean.
when you take and O2 regulator of the bottle, you are exposing the inlet of the 1st stage to ambient air, so it is kind of contaminating it right ?
thanks for your comments, this is new territory for me.
