Hi people - my Aquashphere Sphera's lenses have just popped out, now i need a new mask. I've heard good reviews on the Omer Alien (except for fogging) and thinking of getting one of those. Question - for pure freediving, I'm doing 40m/50m dives now, and want to get something tha't'll suit that kind of freediving, and hopefully deeper up to 60m's. Any ideas? I also use a Cressi Super Ochio, but it feels a bit small on the face.
