Well I am impressed that a commercial pilot is so keen to hang on to history.
You are not an airline pilot and my comments still stand, I personally do not know an airline pilot who uses a whizz wheel.
There is no doubt as you say the whizz wheel is a powerful tool, so was the slide rule and the log tables I used as a kid for math. However in this day and age electronics devices deliver much greater accuracy with less effort and far less room for error.
