Your going about this totaly wrong. Nothing can replace a weight check. Get all your gear and head off to a local pool. Take one full tank and one that's 500 psi. Strap on the 500psi tank and add weight as needed so you can hold a 5 foot stop. As gear and wet suits change your going to have adjust. Also as you become more relaxed in the water more weight will be removed. Then burn off the full tank just working on your control in the water. Paying a GOOD instructor for a few hours would also be a Huge help getting fine tuned. For salt water you can add a few pounds but again a weight check just off the beach would go along way to improving you experience. Guessing or estimating will only make you over weighted and IMHO is just as bad as not having enough weight.Wish someone told me this when i was OW diver.
