I would NEVER be without one. They are incredibly effective. There are many different sizes. Get the right one to reduce your work. I assume you are thinking of hand held? I have a 12-inch for cleanup work and a double headed 24-inch for plot work. Use a 1:1 mix of gly and water. If you are man enough to swing one, it will do everything you want it to do. I guess wicking was more popular when Roundup was $190 a gallon, but, still, being able to play a height differential is butt-kicking awesome!
