Ohhhh I like the looks of that pile hitch, I'll have to play with it.
How easy is it to undo?
I'm using gutter nails which are textured, so I'm not going to be able to easily slide any knot off the stake.
The adjustable knots seem overkill to me. I just guesstimate how long I need the line for the pitch I want and press the stake into the ground. Nothing to adjust except where you drive the stake in.
When I can, i just use the fixed eye I spliced in the end of the guy lines so I don't need any knot at all. Maybe there's situations I haven't run into yet though.
