If anyone has any experience setting these, send me an email. I need to pick your brain.
Oodles of experience back to the middle 1980s.

I'm skeptical about the refusal standard. After you have 20 feet or so of rod in the ground -- unless you're pushing it through muck -- I wonder if enough friction will develop around the rod in most soils to accomplish the same stability without incurring the cost (roughly $25 per foot for 3/4" aluminum, once you figure in labor) of getting down to 1 inch per minute.
