Is there any disadvantage when it comes to being able to ditch weight? With an SS plate built into the harness, it seems that if you needed to get light, quick, you're going to be more weight down than VS a BC jacket with integrated pockets to ditch?
I have noticed the BP/W slant here - like I said, open to either, I currently don't see any real disadvantage to the BP/W so that's why I'm wondering... there's GOT to be some downsides or nothing else would exist yeah?
Can anyone make arguments AGAINST the bp/w?
For ditchable weight there are a number of options including the good old weight belt. However, the BP/W usually ends up balancing the empty tank buoyancy, the wing and harness residual buoyancy and your own buoyancy in your suit.
The "balanced rig" philosophy is that you carry detachable weight equal to the weight of the gas at the start of the dive (usually about 3kg for a AL80 full) and the rest distributed for comfort and trim in the water. Problem at start of dive? Ditch weights and swim up. problem at end of dive? Swim up.
You almost never want to go from negative to very positive, fast. At most you want to go neutral so you are not swimming against unnecessary weight.
The whole "easily ditched weights" idea , IMO, comes from the "weigh the students down so they stay put while I'm teaching them" school of instruction and leads to a huge amount of overweighted divers.
Also, the Jacket BCD with their padding etc etc also tend to be pretty buoyant themselves. Take an empty one and try in a pool and see how many pounds you need just to sink the jacket. thats weight you are carrying for no purpose.
Believe me, your back and knees will thank you for getting a BP/W.
Also, its a lot cheaper when you realise that, for your purposes, you can get a cheap wing and the plate lasts for ever, the harness is 20 bucks and last pretty near forever if you aren't bashing into rocks and metal.
Arguments against? Back inflation systems are a little less comfortable to float on the surface in, takes a while to get the technique down. I use mine like a kids pool bed, I lie on top of it fully inflated.
In every other part of diving I have never looked back.
