Question/ Float and Fly from the North.

Is the Float and Fly primarily a small mouth pattern or do large mouths fall to this technique as well, and has any one tried this tech. in Northern United States. States such as Minnesota or Wisconsin, or possibly the Great Lakes.
The reason for the question the few times I experimented with the tech. all I caught was pan fish, and the occasional walleye. Typical on these outings the bass feel for 1/4 swim jigs and when the bite slowed down I tried Float and Fly. I have had some success on the Mississippi River. Thank You for any replies.

It definitely works on Largemouth and the few times I've tried it I believe I had plenty of panfish bites, but most couldn't take the hook. The first fish I caught with it was a bluegill.

It wouldn't surprise me a bit if you caught walleye on it as well.

I think the key is that it needs to be suspending fish and fairly deep water. With reservoirs in the south, you have a lot of that near cover (shore). Up north, you usually have to get out in the middle. Remember, we're generally fishing about 10 ft. or more down.

It would make sense to me that if you could find a steep river bank that held fish, you'd probably do well with it.

Other than that, my theory is that FnF is just a southern version of ice fishing. It forces us to fish slow in much the same way the ice forces northern fisherpeople to fish slow.

Al Lendere had a show from up north with the fly, seems to me he fished
7 to 9 ft deep he boated some good smallmouth
