I almost fell of my chair from laughing so hard when I read the "Old fat guy that loves to weld" Gerald!!! :) :) :)
Too funny because, that's what I call myself sometimes when I'm having fun with my students during my demonstrations. ;)
I also agree with your advise with respect to proper technique to use when going uphill as you mentioned. :) :) :)
Besides, if you demonstrate what you mention on an open root butt joint whether it be on plate, or pipe - it shows in the results and nothing validates what one recommends like the "proof in the pudding" when looking at the results.
Respectfully,
