Fahrenheit Absolute for me.
I smelled this for the first time in the Duty Free shop @ Sydney airport in June last year, and knew I had to have a bottle. It's very different from the original Fahrenheit, and not just because it doesn't have the 'gasoline' accord.
Although I think Royal Oud is nice, its sawdust opening pushes me further towards Fahrenheit Absolute. I can't wait until the weather cools down over the next few months so I can break it out more often.
