I've seen some random interest and speculation into 26/35/0, and while I've used it for a long time I needed decent weapons before I could really put it together, so since I got S3 swords I've been rocking it.
vs 17/44/0:
Pros: Deathwish, sword spec, imp thunderclap
Cons: +10% threat, -10% AP, no Rampage, only 1 point in precision, fast OH for whirlwind

This isn't an example of blowing everyone else out of the water, but just a simple showing that 17/44 isn't the end-all of specs. In addition to performing as well, you also don't need to watch GCD and timers for rampage.
The main difficulty with this spec is figuring out the theorycraft... all the dps spreadsheets don't account for this spec. Suddenly haste is better, +hit is more important, AP isn't the only focus, and crit... well it is what it is.
I play with other fury warriors who are 17/44, they've tried stacking +hit, APen, and AP, but in the end swords perform on par.
I know I can't be the only non-twin blade warrior using Sword spec, any reason this isn't mentioned as a build in places like the warrior compendium, etc?
