I have a confession to make. I do not understand when people talk about the weight of jigs, i.e. latex lures, and the rods designed to cast those weights, whether they are referring to the weight of the jig head or the combined weight of the latex bit and the jig head?
I have been weighing the unmounted lures using postal scales and there is a vast difference in the weights of some latex lures from around 1.5g to over 20g, but crucially they are sold by length, not weight.
I take the weight as being both the body and the jig head that you choose to pair it with. I wouldn't buy a lure without knowing what weight it is... most of the ones I've looked at - from the well-known brands - do state the weight, as well as the length of course.
But by all accounts, casting weights are only a guide, and (within reason) it's more to do with loading the rod, rather than the size of the quarry.
It's at the lighter end that you need to match the rod to the lure more carefully, so that a rod rated for, say, a 5g lure will actually load satisfactorily, rather than feeling like you're casting a peanut with a broomstick.
I'm only just beginning to fish with lures, but that's my understanding.
