what would you use ?

[blue oyster]

i found a spot that i am unsure on what plug to use . it's a small rock ledge only about five feet wide that drops right off to 15 - 20 feet of nice moving water with some big rocks scattered on it . it was holding fish , i spooked a couple drifting over it , i plan to hit it at sunrise towards the end of the week but because the water is calm at this spot i am affraid that lobbing a pencil popper or big swimmer might spook the fish , casting over and drawing back over not an option . i was thinking of trying a 6" storm , anyone have any other thoughts thanks
