Hey Jordan,
Check out
http://www.bossiadventures.com/ Awesome liveabord adventure with some epic fishing, both jigging and popping, for GT's, Doggies, Grouper, Sailfish and more...
Recent trips have yielded 100 plus GT days on Jigs....mostly fish in the 15 to 25 kilo class, but there are ALOT of HUGE GT's around Madagascar, with very little fishing pressure...
Hope this helps...
Dre
