That's why the lines are to be 10' on each side. With an attachment point height of 36" (doesn't matter if the pole is actually 48" to allow for a tarp) at that length the angle of the guyline to the ground is only 17.5*. I could go longer, but there is a limit to what is reasonable. I just wish I knew a way to calculate how much force I am exerting on each stake, so I could figure a reasonable safety margin and know what angle I need to use.
