Hi Dee,
I've got the ACB+ and I really like it. The only drawback is that it will only hold 7# of soft weight versus 10# of hard weight (per pocket), and both of those REALLY pack it full. But if you're only using 10# total, it sounds perfect. I just did my AOW over the weekend (yay!) and myself and one other person out of 5 were using integrated weights versus weighbelts, and by the end of the second day all of the weightbelt people were eyeing our integrated systems, and the other guy with the integrated back inflation Genesis BC was eyeing the bp/wings! I think the pockets are very streamlined, as unless I'm using a divelight, I have my hands held together near my belly while I dive, and the pockets are in the slipstream of my elbows, not presenting any drag. During our navigation dive, I was cruising along and my buddy in a regular BC was struggling to keep up, and she told me she used to be a competitive swimmer, and I can't swim to save myself (well, you know what I mean). The streamlining advantages of the bp/wings even with the ACB+ still beat a jacket BC hands down. I agree that a weightbelt is probably even further streamlined, then I think about the second buckle, slipping weightbelts, sore hips, etc etc. If you don't need the extra weight, and don't use a canister light, the ACB+ sounds fine. Lloyd Baileys had the best price I could find on them, although 5th Dimension weren't too far behind. Even though they still cost over $110 or so, I think for the luxury of not having to lug a seperate weightbelt around, and being able to spread the load of that weight around the harness and on to your shoulders instead of directly onto your hips while walking around on land, it's money well spent.
My 5c worth (ban the penny!!!)
