Mick ... since you're in Oregon, perhaps the best option would be to dive with a backplate/wing and long hose configuration ... with someone who knows how to use it properly ... and make up your own mind.
OE2X has offered ... FWIW, his tanks are being held "hostage" in my garage ...
... so if you have a week-end sometime to head north, come on up and let's go diving. I've got a spare BP/wing rig and long-hose regulator you can try out ... and either myself or OE2X can give you adequate instruction in how to use it.
Then you can decide for yourself if this style of diving is right for you ...
