G'day Steve,
This site has a heap of awesome info on fishing for snaps with SP's and soft plastic fishing in general. Use the search icon on the tool bar above and you will find enough info to keep you reading for a good month or more. It's pretty simple really mate, just get yourself a quality graphite outfit loaded with braid, a few packets of placcies and jigheads and get out there exploring and give it a crack. It won't be too long before you start nailing a few quality fish, good luck mate - enjoy.
