I am not a big SP fan at the moment but I am interested in giving this a go. Obviously the retrieval technique is key and I am happy to trial and error on that.
But a more basic question, do you let the lure sink all the way to the bottom when you first cast? And how deep of water are we talking about here (e.g 10m, 20m , 30m + ).
I can imagine having trouble getting my lure to the bottom with a bit of current running in say 20m of water.
