The area outside broughton is a good place to start, that then gives you the option of heading south or north dependent on the reports of fish. Keep an eye out for the boats like calypso, viking etc, they tend to know where fish were caught the day before (that doesn't mean you won't catch them elsewhere).
If you have the interclub sked map that should give you (and everyone else) an idea of where most fish are coming from over the weekend as the shootout is on.
