I know I'm going to catch some stuff from a rotating fan, but I've worn many rental jacket-style BCs and never had any problem keeping upright on the surface with the thing inflated, but it was always while wearing a weight belt. I have tried three different BP/Ws and I'm always glad I have my snorkel because I tip face-forward. I have tried numerous backplates and weight configurations and surface techniques and no matter what I try, I always end up face-down on the surface with a BP/W. I can float on my back but it requires some effort to keep from going face-down again. Regardless, I very much prefer the BP/W configuration for many reasons. I dove for my first 43 years or so with no BC whatsoever so having a small donut wing is the only setup that I actually like. I am already moving away from the SS backplate and harness back to the plastic backpack but I plan to weight the backpack, add a small donut, and put the weight in pockets on the sides. The harness in itself, along with the SS backplate, are fine for the most part, but I've always thought the strap configuration on the plastic backpack was the ultimate in simplicity and ease of adjustment plus it's more compact and takes up less room for traveling. Plus I don't need a crotch strap. Perhaps my face-forward attitude is because of some kind of physical abnormality due to the redistribution of body mass that came with old age, but as long as I have my snorkel it's OK.
