No, should stop talking about a fish creating a vibration.  It will greatly simplify everyones understanding of what is happening.  IMO it is way worse than the misnomer of calling a flip a pitch.

Exactly.  Before you described the line as vibrating, but the line transmits force and is the forcing function moving the rod.  If you feel vibrations from a dead pull on a rod it is the mechanical response of the rod that is vibrating and not the line.  Some rods are surely dead feeling in this regard.

Well, it's a fishing forum not an engineering forum and I try to keep things simple and still get the point across. Though like Einstein said," Keep things as simple as possible...but not any simpler."

2) Fishing rods are pretty simple.  You can get a quality rod with the desired length and action for under $100.  The only way a company can justify charging hundreds of dollars for a rod is to sell it's sensitivity.  So companies put a lot of marketing money in to pushing the importance of rod sensitivity and the superiority of there rods.

There are many other factors in the quality of rods and their cost than just sensitivity.  Sensitivity is not the only way to justify higher prices.  Cork quality, for example.  Or other grip materials for better grip, lower weight, etc.  Integrity of the build, as in not using cardboard for seat shims.  Higher quality guides for better corrosion control.  Higher quality seats that don't have plastic hoods that break in a few years.  Lighter for better comfort, if not sensitivity.  Better quality control to eliminate problems from getting into the field.  Yes the buzz word now is sensitivity, but it's not the only factor in the quality of a rod.
