Have found the stimulate pellets in both types to be excellent. Just put them in a mesh bag, dangle off a jetty or add a large weight and sit at the edge of the surf line to let them slowly break up. Can also be fired with a sling shot over a large area to get a trail going.
Theres another brand made from hemp seed I got in picton and they were also good.
Usually I make my own ones from frames, oats and fish oil.
