You missed the part about "don't need a weight belt". I don't like weight
belts, they are just one more thing to screw up and they mess up the air
distribution in your drysuit. You either wear the weight you need on your
back or you add it on with a weight belt, so there are no savings when
climbing up a ladder with HP's.
