Get yourself some 1KG (2.21lbs) or 2KG (4.42lbs) block weights and a rubber belt then see what works best in the shallows so you can calibrate your needs accordingly. Also depends at what depth you like to be neutral. Trial and error I suppose. Personally, I dont like to handle uncoated lead for obvious reasons so I go for coated blocks.
