Hi YF, I have just joined this forum and happy to offer some suggestions.... to answer your question start with a paddle tail or a vibe.
Paddle Tail - I like the 10x stretch material, this material is now used in a few different brands.... if you use the generic rubber compounds then you will find the pickers destroy them in no time, not to mention its probably not doing the fish much good either having chunks of plastic in their stomachs...so you will be forever re-rigging lures and watching $$$ disappear quickly replenishing your lure stocks. A 3-4inch plastic paddle tail is a good size, small enough for a big bream, large enough for a big jew and a good all round size for any size flattie. Lift and drop, touch the bottom and repeat - Its that easy. Make sure the lure is set straight on the hook, if the lure spirals as you drop it then re-rig - if your fishing in 10 meters of water use a 3/8 jig head, if your fishing in 5 meters of water use a 1/4. You want several seconds of suspension time after your flick before you touch the bottom....
Vibes - A single slow lift, you will feel the vibration of the vibe in the rod tip...find that point where you no longer feel the vibration, add a touch so you can just feel the vibration and that's the sweet spot. Again drop and hit the bottom. and repeat. A tight line should be kept with the vibe so when it sinks it doesn't spiral... by nature vibes will want to spiral if they are given too much slack... keep in contact with the vibe and it should sink nicely. I like to follow the vibe down with the rod tip... this way I keep in close contact at all times. Vibes are an excellent way to start plastics fishing, very productive and easy to use... these days you should pick vibes relatively cheap... forget the $30.00 trans-am price tag. Go online and you should be well under $10.00 each for decent vibes. Most cheap lures catch just as many fish, its how you use the lures that matters. Strike up hard if you feel the bite.. I find the smaller bites are often the bigger fish. Good Luck and I hope you make the call Fishonn.:)
