have a word with TerryH off here, he instructs through Calipso. I did my training with them, you probbaly saw what I was like shortly after diving/training with them (Terry had no part in it though) so that'll give you an idea of what they are like
which probably means you'll go with someone else. Pete was/is(?) the owner, he's a laid back Brit.
Mala was and remains one of my all time favourite dives, you wont want to do it with twins though, the entry is a right bastard, the exit worse.
