You should probably look into getting a Stella 18kSW or Saltiga 6000GT/6500 DogFight for such an application. Both those reels would provide you with reliable service against 100+# tuna in Panama, after all, whats the point of having to worry while you're there trying to kill big fish with poppers right? Plus you're already spending all that money going to Panama, might as well get proven gear for fishing there. No need to risk it. JMO.
loved my saragosa 18000. but, for big fish, the drag had me scared. the difference in drags between the stellas and saragosas is astounding. so i sold both my saragosas and no i hang with stella. even if im catching mahi i still feel more confident if a marlin or tuna busts in!
