Brodex, SLX and, E-tel Tried them out i just didn't like them. My pole's don't stick i never get black hands. I have 4ft&18ft Multi Pole, 45ft Ergolitet(E2) Glyder 28ft and I'm about replace the Ergolite with a swift 45ft, and as i have picked up more commercial work the swift 65ft. I'm not knocking other poles or system, but it all works for me.
