I've acquired too much buoyancy control gear which is not oriented towards the diving I now do - (i) top-end but bulky recreational BCD which I bought for deeper or more challenging recreational diving, from shore operators or from my own space-challenged sailing boat. Unfortunately it takes up far too much space on the boat and is heavy for travelling.. (ii) lightweight travel recreational BCD which I bought to be tight/light/compact on my boat and is great for long-haul trips but not confidence inspiring for deeper recreational dives. (iii) DIR backplate/wing for tech OC doubles which I bought for both long-haul tech-trips and on my space-challenged boat when visiting tech shore operators. I'm tempted by the Apeks WTX system to replace the lot. But having only briefly seen the WTX modular set up on another diver I'm a bit unsighted. So if I sell all of the above and buy: (i)Apeks light-weight travel backplate (ii)Apeks safe-weight system (iii) Apeks single-tank bladder (iv) Apeks double-tank bladder Am I going to be better off (obviously not financially!) but from a diving point of view? I'm thinking that the backplate and empty bladders will pack down very flat and compact on my boat and in a suitcase for long-haul prisoner class travel, but can still show up for DIR tech diving? So just how compact are the Apeks bladders when fully deflated and rolled up? Are they a big space saver over a conventional high-end recreational BCD?
