Corkscrew

Couple questions. Armory's at the left if you need it.
(And yes, before it is asked, that is the best I can muster for trinkets - I've lost on every Berserker's Call I've seen, and no TT's, DST's or Madness' have dropped for our guild. Ever. EVER. Fuck this game.)

Question #1 - I usually run a 33/28 spec, but lately we've had a second Arms warrior in the raid, and of the two of us I'm better geared, so tonight I gave 2h Fury a try (not really interested in DW Fury at all, the playstyle just isn't to my liking). Unfortunately, our WWS guy wasn't logging tonight, and we only did Azgalor and Archimonde anyway (not the best DPS tests, especially since on the Arch kill I spent 2 fucking minutes running away from one unfortunate Doomfire after another and ended up in the goddamn Well of Eternity for my troubles, a unique experience I don't care to repeat).

Anyhow, without WWS to go on, my impressions were this - spottier rage generation than 33/28 because of loss of crit from Axe Spec, which led to several instances where my Flurry was down for a decent period. Our dps group usually runs warrior/warrior/shaman/rogue/retpally, with our feral in the tank group (or, in the case of Arch, out healing/decursing). The individual hits were lower as well, and even BT felt like it was landing more weakly than MS, but I'm sure 5/5 Flurry (when it was up) was making up for this. I was doing the expected rotation of 4x Slam/2x BT/1x WW, with very few HS if any, since my rage generation was so much different.

My question, after all of this shit, is... am I missing something? 2h Fury just felt like... less, which seems the opposite of what I expected. Should I just go 31/30 (5/5 flurry in exchange for Blood Frenzy, since the other warrior is almost always there) and save myself the trouble?

(again, I wish I had a WWS to better examine this, but sadly...)

And, much more simply...

Question #2 - I (finally) replaced Fel-Steel Warhelm tonight with Onslaught, which should boost my dps dramatically (thanks metagem!), but it had the unforunate side effect of dropping me below the hitcap with no clear way to get back above it.

I'm sitting at 130 hit, so I have a couple options, and I'm pondering which is the best:

1 - Surefooted, and live with being 2 under cap. Not preferrential, because I love me some run speed, especially on Council and Illidan attempts. (I use Boar's over Cat's because I occasionally PvP and fuck it, 9 more stam).
2 - Arcanite Steam-Pistol over Tuskbreaker. 18 hit would cap me plus some excess, and 19 agi would help with crit (esp if I stay 2h fury), at the cost of a little AP and some meh haste.
3 - Brooch of Deftness over C. of Serrated Blades. This is where my real question is. My (outdated) dps spreadsheet tells me the Expertise/Hit gain is a much lower dps increase than what I lose in ArP and AP from Choker, but then this thread is telling me than Hit/Exp > *. Is my spreadsheet just calculating shit wrong, and I should probably update? The answer to the second half of that is undoubtedly yes, but am I missing something besides?
4 - Redo my Fury spec to dump a point into Precision and just say fuckit. 50g is simpler than changing gear obviously, but would the added Expertise from Brooch make that a better choice?
