Bait and techniques

[Gonzo08]

Ok im not new to fishing i have been fishing all my life but ive only ever used the one technique (cos its always worked). The technique ive used has been a simple worm on a hook sunk to the bottom. So I guess you can say im an amateur at the sport. The thing is i want to start to use different methods ie baits and techniques.Also want to catch different types of fish other than trout.Can anyone give me suggestions on different baits or methods of catching fish. What aits work best for you when river fishing. Ive given fly fishing a go and its not really for me. Thank for your help in advance.
