Only the EDGE EXP has a plastic barrel in the second stage, at $240 MAP it is an AMAZING bargain. The EXP is competing at a price point below many unbalanced first stages (the EXP is a balanced diaphragm) and unbalanced/unadjustable second stages (the EXP is balanced adjustable) The EDGE EPIC 2012 ($320 non cold, $250 cold version MAP) has a Brass/Chrome barrel in the second stage and the EDGE TiExtreme ($699 MAP)has a Titanium barrel.
If you really dislike the plastic barrel, tell any EDGE dealer you want to upgrade to a EPIC 212 for the difference in price and that I told them to send me back the old EXP. I'll make it work for all involved.
My oldest son has an Edge Epic that I bought him for last Christmas. He loves it and says he has no intention of switching brands. I've dived it and I agree that it is a fantastic regulator. I am pleased with the rugged simplicity of the first stage. There really isn't much difference between the Conshelf/Titan first stage and the Edge/HOG. The Edge has two or three fewer parts, which just makes it simpler to service. The second stage, however, is more complex. If I were just starting out, Edge would be my choice. However, I prefer all-metal second stages. A plastic second stage with a metal barrel isn't enough. Plastic seconds are fine as octos, though. This is why I've been collecting Conshelf/Aquarius/Calypso regulators. I don't need adjustable/balanced second stages. Properly tuned, a Conshelf gives me all the air I need without the added complexity. I like things simple. I like the "set-it-and-forget-it philosophy. I tune the second the way I want it and leave it. But that's just me. My favorite Conshelf is my beloved Conshelf 14. It was one of the last ones made a few years ago. I got it military surlpus, NIB.
My youngest son won't even consider trading his Aqua-Lung Calypso.
To my way of thinking, an Edge or HOG first stage paired with a Conshelf all-metal second would be an ideal combination. Now, if Edge/HOG should ever come out with an all-metal second, I would start to drool.
I appreciate the offer but, for now, my Conshelfs fill my needs perfectly.
