Tony,
It's worth remembering a couple of things about fishing in matches.
Firstly, catching fish under match conditions is often much harder than the way you do when pleasure fishing. I've come across people a few times who are used to catching plenty of fish from a water, looked at the match weights and thought "I can beat that easily", and then found that their special method simply doesn't work at all in a match. It's complex why some methods do, and some methods don't work in matches but the extra disturbance has a lot to do with it.
Secondly, fishing matches is all about catching fish and enjoying yourself. You can't catch pounds, kilos, only fish. So experiment constantly, persevere, recognise what works and what doesn't. At first you may find yourself a long way short of the winning weights but hang around after the match and talk to those that did well. Many match anglers are happy to explain what they did especially when bouyed with success but they will expect to hear from you what you did and found out. As Baz rightly says watch some matches but if you do, keep quiet and well back only approaching anglers if it's OK with them. For some it spoils their chances and concentration to have someone blundering around behind them, or giving them earache with a barrage of questions.
Good luck, even if you only enter a few club matches you'll get a few tips.
