I have used:
*Zing-it. My go to line.
*TreeStuff's generic zing-it. Works just as well. The only thing I don't like about it was I bought it from their bargain bin and it was random color. I got gray, and that is pretty tough to see in the canopy of a tree 40' up on a cloudy day.
*Dynaglide. I may like this even better. I have kept this one longer so I use it on higher trees. Maybe I should buy another piece to cut for the shorter trees too...That is the main reason I don't use it all the time. It is a bigger diameter, but it is a little softer, bends easier, easier on the hands to pull, still doesn't knot up or tangle excessively.
*Targetline. Too stiff and rough texture. Don't like it. It is not even in the truck. I have used it a few times to pull wire in the house though...
*Classic Slickline. Used it a couple of times. Never again. Worse than Targetline. Doesn't hold knots when I wanted it too. The strands catch on stuff. Doesn't lay flat. Gets tangled.
Edit: I was being really cheap early on and tried masonry line bought from home improvement store. Don't waste your money trying to save a couple of dollars. Way too stretchy!
