Fly Fishing

Laura F asked:


I am writing a paper on how fly fishing is related to physics and need some averages in order to do calculations.

Average length of rod. I came up with 8.5 feet. Does this seem accurate?
Average mass of rod? Measured in grams, kilograms, or pounds.
Average mass of line and fly?
Average time it takes to move wrist 45 degrees during cast?
Average time line is in the air - measured from after wrist movement is done until the fly hits the water?

Thanks!!
