This one is a tough question - I always feel like Fibonacci is a mind game similar to those math equations where you take the last 4 digits of your phone number, plug it in, and get your age.

I never use it.

One of my best friends who has traded alongside me for the last 13 years uses "exotic" analysis such as Fibonacci, fractals, and Murray math. He has broken down the math, shown me the sequences, etc and given me examples several times during live trading and it seems to work. The exotics are way beyond me so I stick to the whole K.I.S.S. methodology.
