Zanzibar is awesome, spent a month there. You are no pioneer though, its well known to euros. 5 kite schools: 1 italian, 1 dutch, 1 french, aaah i forget what the others but a somewhat clicky scene where they all stick to their own. Not that it bothers an aussie on another continent.
Waves on outer reef at high tide are ok to good.
Sunburn/eyeglare factor extreme 11am to 3pm (think snow blind from whiteness of sand).
Low tide loooong walk, mini lagoon heaven on rising tides, then chop huge area at high tide. Wind every day.
Weed farms on the mid way of the lagoon can be 'interesting'.
Strongly recommend.
