If you gotta wear the weight then why not make it advantageous. Next time you begin to strap on that weight belt think about the steel 77 or 100 cylinders in place of the AL 80. Consider a steel back plate in place of the jacket BCD then improve your trim in the water by moving the remaining weights where needed.
Consider that if you’re using a dry suit you may already require the amount of weight that can make up the set of doubles you have been thinking about.
