Tying to tree limbs works well where there's tree limbs to tie to, but I do my limblining where there are no trees.
I cut poles that are somewhere around 12-14 ft. long and slender. I've used willow, hickory, birch, persimmon, and mimosa. I like willow best, but so do the beavers, so if I use willow, I'm going to loose some to the beavers. They don't seem to bother the other types of limbs much.
I stick the poles in the mud, and wire them to old submurged stumps. I limbline flooded creek channels where lakes have been flooded, and my poles are far from the shore line for the most part. The stumps are where trees once lined a creek.
I like 180 pound test tarred line, a one once round sinker above a real large swivel. I don't remember the size of the swivel, but they aren't the ones you usually find at the local tackle shop....they came from a place called Memphis Net, there a website for it. My weight and swivel are close to the surface, and some might be a foot or so below the surface. I put my hook, on a loop below the swivel. I can change hooks easily like that, and hooks need to be checked often because the points and barbs will deteriorate pretty quickly over the time they are in the water.
I used to use 7/0 kahle hooks, but had alot of trouble with them being straightened or being broken, and switched to a saltwater circle hook....I can't remember for sure , but seems like they were 12/0's. They worked well, but the points and barbs still didn't last long.
I tried some new eagle claw hooks last spring, I believe the line of hooks are called pinnacle, and they are stainless steel circle hooks. I like them very well, and I believe I used the 12/0's.
Sorry I'm not positive about some things here, but my stuff is down in the barn. I can check things later if you really need more detail. You can find those stainless hooks on the Eagle Claw website.
I catch some nice fish, and even though it seems like I use some big equipment, I still get my ass whipped. I have hooks broken off, lines broken, poles broken. About the only thing that hasn't failed are those big swivels and the stainless hooks.
I use live perch, bream, bluegills....whatever you wanna call em. All sizes from about 3 inches to as big as they get. If I don't use live bait, I'm just feeding the turtles.
