Quote:sizes like 2.0 or 2.5 they don't work at all or it's very heavy?Â
 One problem with jigs is that the size description is not a universal standard. This means that a size 2.5 or 3.5 from different companies will not be anywhere near the same size or sinking rate. Sinking rate has a lot to do with the action of the jig as it is jigged, and is a very imprtant consideration in choosing the optimum jig for your style of jigging. Martinetti changed the weight on some of their prawn jigs several years back and the newer ones with the string in the front are too light and do not have as good an action as the previous ones, and if you hold an old model next to a newer model one can see the lead weight is not as big (thick) on the newer ones. I take a soldering iron and add some lead solder to the newer ones, and I also remove the string and install tiny stainless screw eyes to both the old and new versions and get a better action. Now I use mostly the Naorys which have fantastic action with no modifications. The larger jigs will work when the squid are hungry or aggressive, but I find that the smaller 1.5-2.0 jigs work the best for me and my fishing buddues all the time. As I have stated several times it is important to use very thin line (I use four pound) and light sensitive rods when working the smaller jigs as they just don't get as good an action with heavier line and less sensitive rods. The Naory jigs come in three different sinking rates for every size they make and the slower sinking rate ones need thinner line to function at the optimum efficiency.
