Four ten hour shifts is the best. There's really no question, the only sad part is they are inevitably night shifts if you are salary.
Consecutive rest days above two are nothing to scoff at. I've never personally worked three 12-13 hour shifts but from what I've heard, they're the best and the people who've worked them wish they could go back to them.

So what you're saying is... you're a dork?
