Cable Elevators

That's part of it Frank, for sure. Then again it was fairly easy to hear even back in 1994 when my system was nowhere near where it is today, and neither were the cable elevators. Don't forget, mine are tricked out with rubber bands and TC.  

If people are so sure about what they hear, why does what other people say about it bother them? Why do they then feel compelled to discredit others if they do not tow the line? One reason could be they got something to sell. No way to know for sure in these parts so just beware.  Lots of clues. 

Why would those with experience have anything to concede, to those with theories?    Especially: given the plethora of variables, in this hobby.

Since one cannot know the extent of another persons experience, it’s not accurate to assume what they say is based solely on theory. Too many variables in play as you correctly point out. Better to take what people say for what it’s worth and move on.
