Hi Arnout,
I would limit the lures to 12 lures max, Raivavae is more of a jigging destination, however we encounter some good Yellowfin tuna bite and we lost many lures due to shark attacking the yellowfin after hook up,
The GT were active in the lagoon and we discovered a new spot for GT, however it is a very risky spot as most of the hits comes in less than 3 feet of water with structure around, so be ready to sacrifice some lures,
as for jigs you better off putting them and tying them properly with rod strap to the rod butt, by doing so you will be able to save a lot of weight.
Upon arrival to Papeete and when taking the flight to Raivavae you guys have to check the extra luggage as commercial as it is cheaper to do so, the freight section is located next to the domestic flight terminal and that need to be done in the early AM as the freight close 4 hours before flight departure.
you are allowed 20kg with 1 carry on on board less than 5 kg for free, your rod tube will cost you from $50 to $60 depends on weight but has to be checked in at the freight section.
try to see if you can give us a call at the shop so we can fill you with a bit of details that will be very helpful for your coming trip.
