Danny,
We were there last year, and the fish were mainly all at the top end, and would take whatever you threw at them, best bet is have a walk round when you get there and talk to the other anglers, their generally helpful.
It was definate fruit flavours over and above fishmeals in the bait department and orange seemed to be the better colour.
PS By the top end I mean the far end from where the swimming pool is around the island and the outlet pipe.
