A five or six weight with a floating line is a practical starting outfit. Carry an unweighted shrimp for shallow sight-fishing, a small weighted baitfish pattern for cover, and a compact crab or crustacean pattern for fish feeding near the bottom.
Lead a sighted fish and let the fly settle. Move it only enough to draw attention, watching how the fish reacts. A prawn-like start and stop can be useful, but a fly being dragged continuously towards the fish is a different proposition.
Beside structure, stay in touch on the drop. If the line stops sinking unexpectedly or tightens, respond to the weight. Fish the same cover from another angle before deciding it is empty.
