Sawk/Throh is pretty interesting. Sawk doesn't get a whole lot out of it, but can pull off a a Sub BU set just about as well as Throh could, plus Close Combat. Throh on the other hand gets base 125 attack with Guts and decent speed. Immunity to status while changing moves with the power of a CB is pretty flippin' great. Let something with a slow U-Turn/Volt Switch take a hit, let Throh in to wreck some shit.
Against OU Skarmory:
252+ Atk Guts Throh Superpower vs. 224 HP / 252+ Def Skarmory: 178-211 (54.43 - 64.52%) -- guaranteed 2HKO
Actually a bit more than Azumarill's Waterfall, though not quite as much as Azumarill's Aqua Tail.
If you manage to get status'd by something while holding a Choice Band, I think that Throh can do more damage than most anything else right off the bat.
252+ Atk Choice Band Guts Throh Superpower vs. 224 HP / 252+ Def Skarmory: 267-315 (81.65 - 96.33%) -- 56.25% chance to OHKO after Stealth Rock
You know, OHKO'ing OU Skarmory after rocks with a neutral attack, like you do.
252+ Atk Choice Band Guts Conkeldurr Superpower vs. 252 HP / 252+ Def Skarmory: 289-342 (86.52 - 102.39%) -- 93.75% chance to OHKO after Stealth Rock
