OK, Just got back from my first two dives with this bc. Over all I'm I'm very happy with the product thus far. As Scuba446 suggested, the weight of the bc is negligable once you hit the water.
My first dive I didn't have much time to evaluate th bc, I lost one of the weight pouches going down the line and didn't notice right away. I was able to continue the dive, but my ascent was somewhat faster than I would have preferred. Fortunately another diver found the pouch and recovered it for me.
Second dive went much better. I didn't have much time at the surface, but I found it great once I figured out all I had to do was lean back and pretend I was in a recliner. At depth I noticed a big difference. Firstly I found this an extreemly comfortable bc, but that may be because it fits me better than my Vector Origin. Secondly, the back inflate provided much better trim allowing me to maintain any position in the water column.
I only have a couple complaints. The weight and size make it difficult to pack in my gear bag, and I found the air dumps kinda slow.
When I bought the bc, weight integration was the thing I was primarily looking for, but the back inflate was also a good investment.
Steve.
