6'5", 250 36" inseam. I use the long DSS plate and a DR wing, until the long plate I just didn't like a back plate but now I am 100% in the bpw camp, that doesn't mean I can't see some advantage of other stuff like the hydros and doesn't mean I'll ever buy one and having broken 3 sets of novas I'm not 100% sold on the material used on the hydros, time will tell but I have no reason to watch that clock.
I have been diving the Argonaut Kraken almost exclusively for the past several months so my shoulder straps are a few inches longer to allow the plate to ride lower for regulator performance, also dive coldish water most of the time, DSS plate and weight plates make weighting much better for me, I dive a bit heavy to keep more air in my suit to keep out of excessive squeeze which I find causes thigh cramps.
I do try different adjustments but usually end up back where I started, it works for me, I've tried your method and I don't like it, for me.
