Hey! OP here, I have found a few folks locally who are willing to let me look at their set up which will be great. I am still trying to educate myself on these things and I have another question-The webbing:
You should know about webbing: It comes in different stiffness based on the resin it has been treated with. I originally got what seemed like super stiff webbing (OMS I think) and was really unhappy with it - just very difficult to thread and make adjustments to. Then I came across some that seemed to have absolutely no resin (DiveRite, maybe). I'm using that now and really happy with it. Some have said too soft is no good because it bunches and bites into your shoulder, or that it is too floppy and gets entangled when you put it on, or that the D rings move around. I did not find any of that in my case. I also read where someone was succesful in softening up the hard version by boiling it. (The things us humans do...) By the way, I must have told the LDS at least 5 times when I bought my original hard resin webbing "Too stiff, don't like it". All they said was "Don't worry. It'll soften up after a couple of dives". Nothing of the sort. No noticable change after 20 dives, then I got rid of it and got the soft one I have now. (Didn't know about the boiling trick at that time

So what are the advantages/disadvantage-The padded stuff looks more comfortable but is it defeating a point of the BP/W? Some look so padded that its hard to tell them from more a traditional BC.
I bought the OMS deluxe harness a year ago, changed my mind in 1-2 days and returned it for simple webbing. My reasoning was that in other walks of life, middle/compromise solutions often leave you unhappy at both ends, so just go for a good example of any proper solution. The fact is you really don't need all that padding for the straps. Same goes for the padding you can get for a backplate. I used one originally, but don't anymore. But you can use it to stow something like an SMB.
And when you say "hard to tell them from more a traditional BC", Tobin has said something similar (at least once!).
Hope this helps.
