Neko rig fishing

I'm not sure I understand the question. I throw Neko rig around cover but not in it (I fish it with an exposed hook & no weed guard). Any place you can find a hard bottom is nice, the nail in the end can make some sound on the hard bottom.
Here's a nice variation on the rig https://bassu.tv/bass-fishing-video/finesse-chicken-rig-mike-iaconelli
