As stated below, there is much more information on the subject scattered about the Saltwater forum. A quick search should turn up a ton of info by some very accomplished flounder pounders.
I know there have been some good posts on the board regarding flounder tactics and techniques, but I was reminded yesterday that a flattie bite is truly different than any other fish. As I was catching reds and trout when I got into the flat fish, I wasn't prepared at first. I missed three or four nice strikes just because I was in the trout and red mode. I was going for the standard (gentler) hook set as soon as I felt the tap, and I kept missing.
I stopped, smoked one (see previous comment about cigarettes), had a snack, and told myself that I had to let that intital strike happen and then wait....wait a little longer...(convince myself that it wasn't a trout that is now long gone)...wait some more, and then cross their eyes with a huge hook set. Bass are the only other fish I use as powerful of a hook set on. Once I got into that flounder mode, I really started catching them. I still lost 2 or 3 others too, but waiting after the initial strike and the big hookset, really increased my ratio of bites to netted fish.
And there in lies the rub...if you are not specifically targeting flounder I wouldn't suggest the long wait prior to hookset. You'll end up missing a bunch of nice fish and/or end up with a bunch of gut hooked pescadoes.
Hmmph.
