There really wasn’t any play on words. It was the order the sentences where in, so while correct, what I was trying to say was not clear. The second post took care of that.
I will answer your question, with a question - "being a smart butt" myself.

How in the hell do you see the roll (or action) of/on anything 30 feet directly under the boat? I'll answer for you, you probably are not! The action on the bait is checked before it is let out and goes down.
One of the points I was trying to make is the flasher will have the same action to it whether the drop back is three feet, 30 feet, or 300 feet. The only thing that will change is the circle/loop it will make. Which BTW... also makes it travel and cover a larger area of water – THE ACTION IS THE SAME ON THE FLASHER! With a “LONG LEADER” from the flasher to the bait (e.g. “6-10 feet”), the action of the flasher will NOT affect the action of the bait. That nice tight roll of 60 RPM will still be there. That is NOT the case if it has a 42" leader from the flasher to bait!
I have and do, use long drop backs up to 100 feet “AT TIMES” and “if I have a reason”. One reason is using a drop somewhere between 50 to 100 feet, it will entirely negate any effects from a hot boat. That also negates any effects of Cannon PIC system.
Another reason, I like to target large salmon that like to hold close to shore, in those nice little back eddies no one fishes. Three such back eddies immediately comes to mind that are very small and surrounded by shoals. One cannot effectively troll through them. So, I increase the drop back far enough the bait will go over the shoal and as soon as I believe it has cleared and is in the hole (pocket); I put the boat in neutral, letting the bait settle toward the bottom, then pop the line off and start retrieving with small erratic jerks. Can you relate to mooching... while trolling? If you know of a small back eddy, where those large Chinook like to hold (e.g. Conuma 4 years in a very small back eddy a Ferrer Point), you might want to try that – you will love the results!
My normal drop back, most of the time happens to be 25-30 “pulls.” 25 of my pulls is approximately 20 feet. Other than that I will leave with these quotes.
From Cannon:
“It is best to use a short drop back between the downrigger release and the lure. Drop backs of 10 to 20 ft. are typical”
From Hot Spot:
“A typical Chinook Salmon setup is 18 ft. of 30 lb. leader between the 11" original Hot Spot and the downrigger release, and 42" of 30 lb. tail leader to the hoochie.”
“When fishing at shallow depths (less than 40 ft.) for Trout and Salmon (large Chinooks), a longer leader (30-70 ft.) from release to flasher is recommended.”
“The usual setup is 60" to 72" tail leaders and trolling speeds of 2.3 to 3.0 M.P.H. Rolling the bait at 60 rpm will almost always bring results.“
