tactics wise .... you can either roll baits through the swim or anchor them down with heavy leads both catch fish .
Rig wise just standard knot less knot mate for ledgering , with slightly longer rigs . Boilies, pellets , meat , corn , maggots all will catch but boilies tend to target the barbel better than most things halibut pellets are also good but did seem to blow towards the end of my time fishing the Wye.
