The majority of my fishing from my PA 14 has been in the flats of the Mosquito Lagoon and the Indian River Lagoon. It's no secret that you need to be stealthy to get near the big trout and spooky Reds. On the flats, I used the flutter technique a lot as it was faster than poling. I would cut into a flat, flutter until I got closer to where I wanted to fish and then would stand up and pole.
What I found is that I was missing a lot of fish by accidentally spooking them on my way to my spot. I believe that the rigid motion lends itself to accidental clunks on the hull and the short back and forth strokes also create unnatural noises.
I've changed my technique and I now pole as soon as the water is shallow enough to do so. It takes more time but the reward has been a lot more caught fish and less spooked fish. Standing up and sight fishing is a thrilling experience and it's even more exciting when it gets you on the big slobs.
I would recommend you use a push pole that is, at least, 8 feet in length. If you can get a light 12 or 14 footer, that would be even better as the 8 footer really doesn't allow you to use the best technique.
Below are photos of my best catches from poling and sight fishing; a 36" Red and a 27" trout. The trout was also a personal best. The Red was in an area that, historically, I would have been sitting and fluttering and I would have never seen it. The trout was up at the edge of the water so I probably would have been standing no matter what. Both were an incredible thrill and it gets me excited about fishing every time I look at those pictures and it's why I will continue to push pole and not flutter in the shallows again (of course, this is dependent on the conditions).
