Nothing personal to Stuartv but I do have one question which is -
Why are you doing technical diving when you're an experience level beginning open water diver?
Again, nothing personal but your question - "why would I ever want my rig floating at the surface without me?" is kind of a head scratcher. Poor Tobin. I've been in customer service before and it sucks.

Maybe I misunderstood and you meant you only have 50 "tech" dives - sorry if this is so

There are jacket BC's that don't give you that squeeze, but it sounds like you prefer a back floatation B.C.
A BP/W may be your best option depending on the answer to these questions:
Where are you going to do most of your diving? Tropical ( warm water ) or local ( colder water ).
What is the thinnest suit that you plan to wear for diving? No suit, lycra, .5mm, 1mm, 2.5mm shorty, 3mm or 5mm or thicker.
What is your percentage body fat?
If you plan to mainly dive in Ohio & your thinnest suit is a 5mm or thicker & you have a high % of fat, then a BP/W is for you.
If you plan to do most of your diving in the tropics ( warm water ), your suit is 3mm or thinner & you have a low % of fat, then a BP/W may be a poor choice and even hazardous.
It may be a poor choice because you may find yourself overweighted. This circumstance will lead you to having to put too much air in your wing ( B.C. ) making buoyancy more difficult.
A BP/W may be hazardous due to the fact that you will find yourself overweighted without the ability to drop weight in an emergenc
If the above is true then I must be dead already. We dive all summer in California's Channel Islands in steel 72's, shorty wetsuits or a vest and swim trunks. Steel, AL or Kydex plates/packs and no BC's.
Some of us, obviously don't wear lead on belts and some of us wear maybe 4 or 6 lbs. We dive the oil rigs, frontside Catalina, Farnsworth Banks, Begg Rock, wherever - it's all the same.
If if you can't swim up yourself and your rig at any point during a dive without a second thought, you haven't been trained in buoyancy control and weighting properly and I am talking SPORT DIVING here. Single tank / Double Tank recreational diving and shooting fish type stuff.
Check out the diving sequences in "Thunderball" sometime. You'll see dozens of divers doing some pretty regular diving in nothing but packs and tanks - as far as I know, they all survived, even Sean Connery was almost attacked by the Bull Shark who broke thru the barrier in SPECTRE Shark Tank
