My "conventional" Nighthawk BC (on eBay, by the way, if anyone wants to buy it - its only got about 20 dives on it!), weighs 9lbs. It is roughly neutral (Scubapro does get THAT right - not all do, as some BCs are positive!)
My BP+Wing weighs 12 lbs. But its 8lbs NEGATIVE! Only 4lbs of that is "dead weight", .vs. 9lbs for the Nighthawk.
So let's work this one out, shall we?
With the Nighthawk, I need 15lbs on my belt with an AL80 and a 3/2 wetsuit. My kit weighs 9 +3 (reg) + 32 (AL80) + ~6 (weight of air) + 15 (lead) = 65 lbs. I exit the water with 60 lbs on my back assuming I leave some of the air in the tank (I didn't need my buddy's octo

)
With the BP+Wing, I need 7lbs on my belt with the same AL80 and the same 3/2 wetsuit. My kit weighs 12 + 3 (reg) + 32 (AL80) + ~6 (air) + 7 (lead) = 60lbs. I exit the water with 55lbs on my back assuming I leave some of the air in my tank.
Now you say "what's 5 lbs". To which I reply, "nearly 10%, and definitely noticable!"
What did I get for my 5 lbs? A kit that has weight integration and doesn't require a belt. A kit that is less adjustable, but can be adjusted far more quickly. A kit that probably traps a lot of water on the way back on the boat, meaning that my 60lb "exit weight" may be hopelessly optimistic (water weighs 8lbs/gal, you know!)
Choose your poison.
My sole issue is that if you're claiming to be serving consumers, you darn well ought to try to make recommendations that make sense, not just ones that make you money.
I mean, let's be real. If the simple question - "are you EVER going to possibly dive deco, in a cave, or in an overhead' was asked, and if the answer to that was either "yes" or "maybe", then why are you selling someone a "conventional" BC when all that needs to be changed on a BP+Wing is the wing?
At least they did me ok with the reg....
