Well, I don't know about that. I am very comfortable and trimmed in my jacket or vest style BC. If anything I would say it tends to position my slightly heads up/feet down (weight integrated Mares Frontier). My BP/W DEF. positions my head down, wayyy down, and I like to add some trim weights near the bottom of the tanks to flatten me out without having to fight with it all the time.
