raposarose:I use the same pockets as scubaroo and I also like this set-up a great deal. I use a single tank rig and a thick (2 piece 6.5 mm) wetsuit. The weight is easily ditchable with a bit of practice and is more comfortable to me than a weight belt.
As for the Tobin plate, I haven't used it yet but if I get in the market for one (and I may be soon if I upgrade my wife's plate) it seems like a pretty good option. A bit more pricey (probably the main obstacle) than some of the others but it seems to have a lot of attention paid to the details.
You can also add a weight pocket to both cam bands (slide them towards the wing). I ended up reversing one of my cam bands so that I have one weight pocket on either side of tthe tank
