i use a banana sinker thing whatever they are called eh .. have a wide range of weights mate depending on current and depth ..
i run 10-12 lb yo zuri on a shimano curado .. tie on the sinker and have about a meter of 15 lb yo zuri to a baitholder hook about the size of your thumb fingernail if you know what i mean ? ( dont know actual size sorry )
but the baitholder part is nessesary .. to hold the silvery on for the cast ..
hook the silvery through the head strait through just behind the eyes and i sometime do a second one through the body .
i fish it as a dead bait .. ( as if it is dead and floating ou the mouth and is an easy mean for any fish )
most of the fish i catch is when i leave the spool free as it drifts out the mouth then when winding in the slack line you feel the kicking
silveries outfishes lures for searuns and kahawai mate !! the way to go !
GOOD LUCK !
