Scon,
I ve been gamefishing most of my life and have fished with Ross and Glenn Hunter for over 10yrs as a crewman, catching nearly most our marlin on 24kg line class including 21 marlin in day, too many grand slams to remember and some large Striped, Black and Blue marlin.
24kg line is not as harsh on the body and the fish as well plus having a great skipper behine the wheel helps alot too.
Gamefishing is all about fun with great mates and catching that fish of your dreams.
