I love the Sleepers, but they're still not long enough for a night's sleep. I can fall asleep almost instantly, but with JFK sleepers, I get woken up from a deep sleep at T-40 and jump out of my skin in the process.

I have a slight preference for DFW, just long enough for a quick meal service and an 8hr kip. It leaves a tad early, but nothing some melatonin can't sort.
