That is 7 questions tic-toc ;-)
(just kidding my friend ;-)
I will try to attempt to answer only one:
"How does one "rate" the gong sound itself ?? "
- VERY SUBJECTIVELY - despite some commonly accepted criteria for frequency and duration of sound are taken in consideration.
There is a large bias applied when talking to fans of various brands.
For example - here, many would take ANY 'simple' PP minute repeater over a lot more complicated repeater from another brand.
