You could also try a light scandi head. Rio makes a 210grain. You could cast this over head but would have to slow things down. More likely you may want to make one or have it made, my guess would be between 150-170 grains. I used to use shooting heads on my surf rods and lake rods all the time. They shoot like crazy but you need to weight for them to get the most out of your cast and not over load the rod.
