From that report, I'd go with 'Explosive decompression'. Only thing that gives me pause is the relativity of time. When you're dying, 11 seconds could seem like a lifetime, or it could all just happen too fast to figure out what the heck was going on. I guess the trick is to NOT know that you are dying.

Which one would you pick as the best/easiest way to go?

I choose...death by killer rabbit.

Decapitation all the way.

However, in my case it would have to be a really large blade.

I've been real close at least 5 times. ( 2 drownings, 2 asphyxiations and 1 head trauma. Only one was intentional. ) Every time there was a point where I really didn't want to come back. Compared to living getting ded is rather pleasant.
