Old dive supervisor told me to switch from steel to aluminum tanks on a 100-foot wreck dive
He said the weight difference would save my back on the swim back to the boat, but I argued the extra buoyancy was a hazard in current - what do you guys think, is aluminum really worth the trade-off or was he just pushing cheap gear?

Ah man, I've been in that exact spot. Aluminum is fine for recreational stuff but on a 100 foot wreck with any current at all you're gonna be fighting that extra buoyancy the whole way down and especially during deco. I'd rather deal with a sore back for a few minutes than get blown off the wreck because I'm too light on the bottom. Stick with steel for deeper dives with current, your supervisor probably just didn't want to haul the heavy tanks around on the boat.

Dropped a steel 80 on my toes once, still think it was worth it.
