I have fished Samoa many times, you will love it. Like anywhere the remoter you go the better frm the shore, hire a car and if in Apia go have a few vailimas on a Friday night with the locals at the fishing club on the marina. If land based and after gts I wld go the 80lb set for sure, you have a short window to stop em. Some great land based spots at end of savaii with very big gts in residence. Plenty of good charters to choose also
