Actively feeding fish may move from the hole to the edges of the shallows around the rocks where you have caught them before. Those foam lines represent a constant source of feed which the fish will use as a feeding station while retreating to the safety of the deeper water when disturbed. If I were to try to fish the eddies I would use a weighted streamer. Cast it near the hole from above and mend to let the current carry it into the hole. Then take up the slack and let the current swim it out and across. This method seems to work best at first light when the big night feeders are still active.
