Most of my diving is as a DMC w/ classes at the lake, so I use AL 80's. I have a Zeagle Brigade, which comes with a 35lb bladder. I just switched the bladder to a Ranger LTD bladder w/ 44 lbs of lift. I use the DUI weight harness, and put most of the weight in that harness, and then trim out in the BC ditchable pockets.
