do take note there is a different between integrated weights, and trim weight pockets. integrated weight systems are usually quick releasable. the scubapro system seems pretty sturdy and not prone to dropping out like some of the other brands. you have to be careful of those that have a little red handle for dumping the weights.

trim weight pockets are usually at the back of the BC, and are not "dumpable". they usually fit 1 or 2 pieces of weights only.

when choosing the BC, be sure to ask the cost of replacement weight pockets!

if you have an odd number of weights, you might tend to roll towards the heavier side underwater. However if you are pretty comfortable underwater it's not a big problem. i dive with 1 weight sometimes in my trim pockets and it's not a major irritant. maybe because i have my heavy camera clipped on the other side?

another way is to have 1 weight on each side, then have the 3rd on the tank strap if stability is very important for you.

i think brand doesn't matter as much as whether the BC fits you well, and if you like the features.
