I just got mine this week. I have to say I am super pleased. The comfort of the monoprene harness is amazing. It feels like it was custom made for me. I am sure there are people that feel like a floppy harness is just as comfortable, but it doesn't feel that way to me. It is kind of like the difference between a comfortable chair and a park bench. Plenty of people have no complaints about a wooden bench. I'm just not one of them. I can also see the comfort factor discounted more by those wearing thicker wetsuits. Once you get to 5mm or more, I think the comfort of the harness becomes irrelevant.
I like the attachment points and really dig the travel bag. With the Air 2, and the full harness with weight pouches, the BC comes in a little over 8lbs. Its not a featherweight, but not bad either. I plan to add a few of the accessories as they become easier to come by.
