I think you nailed it on the head. I currently have soft weights because they conform better in the weight pockets and are not hard when I bump my arm on them. But they take 2-3 days to dry out after diving, and it’s hard to get all the salt water out, so they leave a salt residue on the table I dry them on. I actually plan to switch to hard weights with the rubber coating after my soft weighs rip a hole and go bad.
