had a bit of a mess about today , with just using 10lb mono and a split shot to sink it , I was surprised to see that the rig will sit upright , the hook is just tied on with a blood knot and the whole lot pulled through a popup and pulled up so the knot just sits into the bait , it does wave around a bit , so by using a stiff hook length im sure that it would work for those fish that only mouth the bait rather than sucking the whole thing in , for those that are interested its a size 6 hook and a 15mm popup .
