I'd also add that rather than starting with the number one arm and then 2,3,4, go in reverse order by starting with extending out the number 4 arm first, then 3, 2, 1. This, for me Atleast, drastically reduced setup time and is much more efficient and easy. I setup up my ez slalom 3-4 times a week and can do it it with three people in under 15 minutes!
