Those Zim private dams ussually have massive bass in them, my advise do not go with line lighter than 25lb and scale up. You can start of throwing your standard lures to determine the size of the fish but in general in Zim the bigger the lure the bigger the fish. Make sure you have top waters, Zara Spooks work well 10" Senko, big Brush Hogs, Jigs and I see you now get Jumbo flukes as well, Big crank baits, spinner baits.
Safety will not be an issue if you are hosted by the farm owner.
HOLD ON to your rod you will have FUN!!
