I'll lower the tier, and realistically speaking is any realism in Terraria?I agree, if you're able to swim down it isn't different at all from flippers and it would in fact be better in that you float without having to press anything and go down at will.
Maybe combine them so you can have the ring and flippers enabling you to swim at will and float like the ring.
Also realistically speaking, I don't know about you guys, but I can't swim down while on an inner tube.... They are pretty well blown up and makes it really hard to go under water.
