Tryonos 30 trolling step up and lures

 Hi guys, I'm heading up to coral bay these holidays and have purchased a tyronos 30 with a 15kg backbone rod.  Have put 15kg mono on and will mainly be targeting mackies and trying to land our first billfish!

 

does anybody have any tips/ secrets for targeting them lure wise, location, rigs ?

 

any help will be greatly appricated!
