Apeks SS backplate, DR Deluxe QR harness (let's don't go on about plastic), DR 27# travel wing. I'm VERY excited to be moving from the jacket BCD to BP/W. So far only 2 hours of pool time, but everything seems to fit and work perfectly. Even my buoyancy with a 3mm shortie, Lexfer AL80 at 12' was exactly where I anticipated to be without extra weights.
I have an Apeks SS Backplate & love it. Also have the DR Delux harness (However without the QR). I use these for my doubles & both are very comfortable & quality stuff. I don't dive a BP/W for recreational diving, but to each their own.
