Mine were copied from @denots and are cut to about 15" with about 13" between the steps. This method drills 2 new holes through the standoffs so you use the same bolts for the step and standoffs and eliminates 2 bolts in the process.Staring at my Heliums that I cut down to 26" wondering why I wouldn't be just as well off if I cut them down to 15" or so...
I don't think @redsquirrel still uses them, but you got any reason for me not to do this?
@Bwhana didn't you run a very mini Helium?
For the moment, I would just have 3 sticks, but I think three mini Heliums plus my platform would get me 18'
