I usually do both. Set some lines out and then walk around casting or sometimes I just grab my medium light pole and walk and cast. Sliding weight around an ounce or so, swivel, 1.5 to 2 foot of leader, size 6 or so khale hook, fishbites tipped with pieces of shrimp, just cast and retrieve or jerk and retrieve or whatever works, should get you some whiting, pompano, or flounder.
