Well that was almost too easy. 28 feet in an afternoon. Wow. In my area, I would just call a drill truck. The whole area is on top of Mammoth Cave. Rocks the size if basketballs in clay or limestone. Good for you, bad for me.

Did you decide what size compressor to rob from its home? If you are not going to push your COP with a critical charge and high evap temp or use an expansion valve, I might just call it quits at 28 feet.

Propane is sort of the opposite property wise compared to r22. Low molecular weight, high heat capacity, less viscous. More will flow through the same cap tube vs r22, and the engineers say run a shorter cap tube. I never have, and everything worked out ok for me.
