Cheers for the replies guys, looks like a new wetsuit is on the list then followed by a rubber weight belt to replace the useless webbing one!
The beaver suit is plenty warm enough (if not too warm as soon as you step out of the water) but a real pig to get in and out of, weighs a ton and is extremely buoyant.
