Have to say I'm horrified when I see those one metre plus breaker bars in use to tighten spinners. The torque they allow such to be tightened to is scary in the wrong hands. Having said that you may need one to undo spinners over tightened by same, fighting fire with fire!
I admit to owning a 600mm breaker bar but use and carry with me one of those pressed steel spinner tools, little over 400mm in length. A few heaves on that tightens and removes to what I regard as sensible torque.
