Here are a few surefire ways to get your feet wet with soft plastics. If I need a fish, this is exactly what I have tied on.
1. 1/4 Buckeye Lures Spot Remover with a green pumpkin Zoom Finesse worm. Take the tail of the worm and dip about 1/2" of it in chartreuse colored JJ's Magic, which is a worm dye and also a fish attractant. This will help the fish hang on longer, which will help you learn what a fish feels like compared to the bottom. Cast the bait out and let it sink. Then, position your rod at the 2 aclock position, then raise it slowly to the 12 aclock position and give it a few seconds to sit. Reel in the slack and repeat until you feel a tap, tug, or the weight feels "mushy" which means the fish is running towards you.
2. Take a 3/32oz Picasso Shakedown jighead and put a *** Finesse Worm in Watermelon/purple color. Make sure to make sure the hook point isn't exposed so you don't snag on the bottom. Cast it out and let it sink to the bottom. With a little bit of slack in your line, give your rod tip a few shakes. Pretend your shaking someone's hand when shaking the reel. This is a basic way to start learning this technique. Ironically, it's called "shakyhead"
3. Lastly, take an *** Trick Stick or any other senko style bait and tie on a small Gamakatsu Finesse Wide Gap hook in the 1/0 size. Pinch the bait in half, then put the hook right through the middle of the bait. When you let go of the worm, the hook should be impaling the worm right through the middle, and each end of the worm should hang down to the side. You don't want to fish this bait with any weight, but it takes a bit longer for it to fall. The slow fall and wiggle is what makes this rig so effective. Cast it out and count to 30. If you see your line jump at any time, set the hook. If no fish after 30 seconds, lift your rod tip up a foot or 2 and repeat the process back to the boat.
If you do any of these 3 techniques for a hour or 2, I guarantee you will catch some fish. The biggest key to fishing plastics is learning to fish them slow, learning how to use them to learn bottom composition, and learning to detect the light bites!
Good luck dude! Hope this helps ;D
