If you want to go with a BC, I highly recommend the Zeagle Ranger.  It has a back bladder with trim weight pockets so you don't get squezed.  It is weight integrated, but when I do cold water diving, I add a weight belt so the BC doesn't get too heavy.  My weight belt has suspenders and is not ditchable, but doesn't slide down my butt at depth either.  The Ranger has plenty of D rings for clipping accessories and storage pockets plus is capable of setting up doubles, but not with large tanks unless you install a bigger bladder.
