First of all, fluke are an aggressive fly feeder and you should not have any problem connecting into them. The challenge here is finding them and presenting it down where they are. Since you fish the North shore / Huntington Harbor? this gives me a good idea where you fish and here are some of my approaches.
First of all? fish the early hours and your best bet is during the ebb (outgoing) tide! Along the harbor banks you will find sandbars, drop off and cuts along the marshes? a sinking line and a green/white/ glittered clouser will usually do the trick. Cast it to the bottom and make quick 2? strips and keep working the spots.
That is correct?. A 7 or 8 wt. outfit should do the trick! As far as line is concerned, you can?t go wrong with Courtland, Scientific Anglers or Teeny sinking line.
Also, under the normal conditions?. It would be a good idea to up one size to give you the power to cut through the wind. In addition, the water you fish can be gin clear at times, therefore it is a good idea to have a Fluorcarbon tippet.
