In god's hand
Hi,
i haven't seen Endless summer 1 or 2. The only surf movie i saw was "In god's hand". Very good movie, but no monokini in that one. Why your brother would bother anyway, i didn't know you kept it in the family down under

rofl
Btw, there's not much monokini around where i live (Britanny, north west part of France) we get more of them in the southern part, more wine, hot water, nice beaches, good vis, bigger fish etc etc also.
What are the diving condition around your place? Depth, vis, tide, marine life etc...etc... Here in Britanny we have 15' vs, 30-50' deep average near coast and a tide that can reach 12m difference in 6 hours... That make for strong current, with water temp round 4C in winter and 16C max in summer. The marine life is VERY abondant but, mostly all small fishes.
