From what I have experienced, read and been told most (certainly not all I'm sure) would use Quattros over Twin Jets for snorkeling. I own both and If I were to snorkel the last thing I would reach for would be Twin Jets. JMHO. Actually, if I were ONLY going to snorkel would I buy something cheap and be content as snorkeling doesn't really require much effort from your legs, just a small kick to move you casually about. Snorkeling and speed don't usually go hand in hand in MOST cases. Good luck! Again, JMHO.
