True, a lot depends on conditions. And 25G less than 50 feet is very
strong and can take a lot of punishment, even having joints not
tightened correctly. I have climbed towers with loose joints above a
hundred feet, and it's rather unnerving!
As for stainless hardware, that's fine - as long as you know what you're
doing. Stainless uses a different strength grading system, and you need
to use the right anti-seize compound if you want to be sure of taking
the bolts loose again.
