i'm a believer, at least for senkos. At my home lake here in Austin. I fish the same shallow water set of boatdocks that are in a small secluded area off the main lake. I hit this area probably 40 times a year, with the same setup,,,,6 inch wacky senko on a 4/0 bait hook on a 25lb flurocarbon leader on a mono main line. I fish it all times of the year. Two years ago i made my usual flipping pass thru the docks. There is probably 30 slips in 2 to 4 feet of water. i caught a fish or two. I had some of the red hooks and thought, Why not. I did not have much confidence at first. I used the same bait hook in red, and got bit again like it was my first pass thru the area. The next time out i swear i got bit more, and it increased my confidence. That spring i caught a 27inch 10.6lb spawned out female out of one of those boat slips on the red hook. I had one set of tires that i'd flip to each time...about 70% of the time i'd catch what seemed like the same 3lb fish. I started calling this fish "Rerun". I fished some small jackpot tourneys on the lake, and i'd tell my partner that on the way back to the weigh-in that we needed to stop and catch "Rerun". And Rerun was there both times!
