Ok so ive read this entire thread and ive seen quite a few things i agree and dissagree with.
First off for the tanking issue. I find that any warrior in any comperable tanking gear no matter what his talent build is "Can" tank but only if at least somewhat skilled in there class. I use KTM threat meter as a must with my guild to monitor threat but even without that. there are so many abilities in Battle and Deffensive stances to hold aggro and deal with it efficiently. And this does include thunderclap and demoralizing shout which will better help you as a tank and as part of the group. But with Mocking blow, taunt, sunder and countless other interupts along with Mortal strike in a tanking fight does help. Ive had long disscussions on the fact of how much MS can help in a bossfight and i do understand that you do loose that percentage of free threat from the Prot tree when you dont get Defiance but i see it as gaining more damage and crit and gaining survival skills such as Endless rage and Second wind. The big downside is the fact you drop quicker in health. But as any warrior should know, your main concern in any group is to have a good healer who can stay focused and keep the heals on. And thats my piece on that subject. Now on to another.
I see all these builds that go back and forth and i do see how some of them could be quite effective. Ive speced all three tree's pre TBC and found i loved Arms and never fealt the urge to try anything other then DW/Fury. And while its an amazing setup for an almost DOT feel i fealt more vulnurable and open then having the massive white damage ontop of the intants such as MS, OP, Thunderclap and others. And find that Arms is the more cookie cutter of the ways to spec but it is tried and true. My personal spec is

Ok and in leaving i read a few posts back on here how the DW/Fury took the adds that came along and made it sound like its hard to take many mobs while in arms and all ive got to say is.
Sweeping strikes + Retaliation + Whirlwind (rinse and repeat) = Whirlwind of death
