On my boat I use a stradic 5000 and mh star seagis rod, and it's more than enough for yellowtail as long as the cuda's/sharks aren't around. When I need to get them to the boat fast I use a bg 30 on a star deluxe. When I fished the head boats, the light stuff stayed at home, but fishing that light stuff is a blast, but you will lose some big fish to the tax man.
Monster cuda smashed this red grouper boat side on 12lb test
I love yellow tailing
