weights

Congrats on finishing up the open waters!
best thing to do on winter vacation (if you're flying) is leave the lead at home and just use the dive boats/shops lead. If you can get in a shore dive first thing, then you can spend time getting your bouyancy right. If you're off a boat first thing, talk to the crew and dm and they'll have a pretty good idea (sometimes) of what weight you'll need, at least it will be a place to start. I don't know of any good formula for weight freshwater/thick suit verses salt water/ thin suit for calculating lead needs. (because I freedive and have ran into situations where dive shops wouldn't rent me extra lead because I was "just snorkeling", I end up always packing my lead. it's the pits.. fortunately between my wife and I we get by with 10lbs.)
