You might like to try casting redgills or even jellyworms behind a drilled bullet. I have been to the tackle shop and they look to be around 7,00. The advantage is that once you are in practice, you usually get to take them home again so they're not really so expensive after all. As I have mainly ledgered and float fished, this is all new ground to me. They're all lures.
Some lures are plugs, some are spinners, some are flies.
Try to keep out of sight, move quietly and matt varnish your rod. You will find polaroising specs useful for spotting fish. Waders are an advantage in many places. If you cast a long way you will find that many fish hit the lures but are not hooked. Line stretch and bow is the problem.
