hi, i am think of buying these s/ps http://i23.ebayimg.com/07/i/000/e8/f7/f9d3_1.JPG ,]has anyone use them for bream before and are they anygood.also when using s/ps like the one in the link can you cast and leave those s/ps in the water like bait or do u have to cast it back in so it simulates moving bait for the fish.can u attach the s/p onto any hook or does it have to be a jig hook and lastly do u use a sinker and if so do u just attach the sinker like u would when using prawn bait.thanks
