Right, I'm guessing you go for all the cheap lures??? lol
I only use barra classics, RMG scorpions (hard bodies) and squidgies (soft plastics). You need to get a range of colours and sizes, once you have used them all you will come up with one or two colours and a specific size that work for you over anything else in your spot.
Out here it is black and gold in 120mm hard body, green in 98mm hard body and drop bear or black and gold or green in 60-80mm soft plastic.
I hate soft plastics, i drop so many fish on them but sometimes it is all that will work. I find they work best moving with the current worked really slowly on the bottom and hard bodies in a very jerky slow-medium retrieve. You will probably find that the fish will hit your lure when it is stationary in the water for split seconds between jerks.
And i've tried the whole single hook thing. I don't like it, yeah you don't drop as many fish but you don't get nearly as many hook ups. In the end i think you catch more on trebles.
