I have used this method with limited success. I have not used it in extremely cold water though. but I have been trying a couple of times on and off for about 5 years.
I would love to know if you have been successful at this.
I caught a few dinks on it on pool 5a one day. but not enough to keep me going on it. I tried it on the upper end of Logan Martin.. We had stacked bass on the mouth of a quarry up river. but no hits. even thought the bass were there and biting 4 inch worms.
I do, however, have one rod rigged in the boat with it at all times. or did for the past couple of years.
I would use a three way swivel at the bobber instead of wrapping your line. Especially once you establish depth.
I am using an old 6 1/2 foot glass rod for this method. There is no feel involved. and you want as much forgiveness as possible if you are using 6 or 4 lb line. I was using 8 which may be a touch too much for bigger fish.
Fishing University did a show on the method, but only caught like two or three fish. a little disappointing.
but if you get on them, You will be one of a very limited few using this method.
and Blue Fleck.. I still have line on my reels. and Still available. License is still good, last time I checked. Just to let you know.
