A little vanity is not an entirely bad thing, Lord Flashheart, I mean William. We all like cool stuff....
@ Mr X: Nah, invisible wouldn't be my style. One of the reasons I was attracted to this sport was the cool gear. The long, elongated fins, the steeamlined suit, the black mask, the marsaillaise belt, the no-nonsense approach and the aire of aloofness. Does that sound arrogant? Yeah, probably.
OK; if you're a spearo I suppose you'd like the invisible cloak idea. I'm a freediver and I'm not just a vain F***** no, I'm a flashc*** too. No Vantablack for moi.
