I have four Worthington steel 100's and couldn't be happier. Ace is right that you will be able to drop a lot of lead off your belt - I drop eight pounds versus using an aluminum tank. And having 100 cubic feet of air is 20 percent more dive time per tank than 80cf. Be very happy with the gift.

And, yes, tanks stay home when travelling by air. Weights and tanks are always provided by dive ops.
