Get AL80's not steel tanks. Practice getting used to them because when you travel most live aboards and resorts only have AL80's. Diving doubles? Get double AL80's for the same reason

If you need a lot of weight to sink, strap it to your tank with a shortened weight belt. Example, with a 7mm suit I strap 8lbs on the tank and carry 8 lbs on my belt
