I've been having buoyancy problems with winter gear with my wing as it won't carry all the weight I need. I tried a weight belt with 6kg in the pool night on Friday but it had dropped off my (lack of) hips in minutes. I've borrowed a Scubapro harness that has two enormous integrated pockets and trim pockets that I'm going to try in Scotland next week. I need 12-14kg, plus backplate - this would work with 5kg in each integrated pocket and 1 or 2kg in the each trim pocket - I can then remove the wing integrated pockets that will only take 5lbs (2kg ish). The Scubapro harness appears to be out of production; the only one on sale is a Comfort harness that is over the top with padding, chest strap and crutch strap. Other suggestions welcome.
