Currently, diving a Department supplied rig with a 7 mil farmer John, I need 20 Lbs of weight. We dive the Apex wtx Harness system with a single Al 80 and 30 Cf pony. After fighting with a weight belt, I've decided to purchase the WTX surelock weight pouches for it. Does anyone have any tips or experience with them? They are a little pricey, but I want to stay within the Apex Brand. Any info would be appreciated.
