I give out my worm technique that catches so many big trout for me on the colorado river in private messages. I'm sure I've probably posted it on this board as well. In short it is much how a flyfisherman drifts a nymph, barely ticking bottom.
As for curly tail grubs for trout, I like casting out into a spot with moderate current that looks to hold brown trout. (rainbows take curly tails, but not with the will of brown trout who like them about 1/2 as much as a presented nightcrawler.) Cast out at about 1 oclock. Let the current do the work, let it sink it to the bottom and let it make the curly tail spin. Every now and then, give it a sharp jerk. When it is out of the current and parallel to the bank, or if you are fishing a hole without current, sink it to the bottom and real it in steadily so it is ticking bottom, or you can sink it to the bottom and retrieve it in a series of lift falls and pauses.
As for bass fishing, for soft plastics jerks like senkos and flukes, most people I've seen fish them TOO FAST. Cast it out, let it sink to the bottom, it may be a bit time consuming but you get a lot of hits on the sink. Now, just twitch it back in with a soft twitch every few seconds, but always make sure the senko or fluke is near the bottom. I've really seen few people fish them this way, but it is really dynamite, especially this time of year when bass are slow moving like this technique is. Hope this helps.
I've already described snap jigging for walleye I believe, with 3/8 oz. crocodiles and the new buckshot rattlespoon, but I'll do it again. Cast out, and sink it to the bottom. Then give it a sharp jerk to the side, let it sink almost to the bottom and wiggle your rod tip back and forth, let it sink to the bottom. Give it a sharp jerk. Let it settle near the bottom and wiggle your rod tip back and forth. Repeat...repeat... Of course you can vary the retreive but this works well. Having never trolled for walleye I don't know what that's about.
I could go on forever but those are my very basic ones.
