I have used every menace arm made, including fabricating my own. The best one for me was the modern menace arm. I always used speedrail. Never over the overall length of 20'. Of course that is depending on what I am putting on it. One thing that might seem obvious but seemed to sometimes be overlooked is making sure you always have one leg of the stand forward, pointing the same way as the arm is extended. The straps help but dont over crank the support straps.
