In all the years I fished the Narrows for critters, the one key to success (other than fishing the slack) was LIVE BAIT. Normally lings will take anything and we CNR them all day long up in SJ mainly using jigs, but at the Narrows where the tide change is very narrow live bait makes ALL the difference. The best tip I got on this fishery though was to forget about buying bait and head out well before the tide change for a bait ball or a back eddy near the point and load up using a herring jig. Another reason for this was because of the size of the bait. Many were easily 9" or larger, some were huge this time of year. We called them bull herring. Lings loved them. Which was a good thing because you might only get 5 or 6 passes over the old bridge debris before the bite was off.
Oh ya, don't forget to aeriate or recycle water to keep the bait active.

Ling'on!
