After finally getting around to watching last night's episode of Impact, I'm leaning more towards Angle now (even though I originally voted for Sting).
Sting has been TNA champ for a really good chunk of time in 2011 already (who else was champ this year? Only Jeff Hardy & Mr. Anderson, right?), and I think it's time to let another "fading" star (Angle) have a run with the belt this year.
Let's face it: neither Sting or Angle have a lot of time left in the ring. Angle probably has more time than Sting does, but that doesn't really matter here. The reason it doesn't matter, is because Angle will soon be off TNA TV - right? Isn't he leaving so he can focus all of his attention on the 2012 Olympic Games?
With that in mind, I think TNA is going to let Angle have a short-run with the Championship (up until it's time for him to be written off TV). I think having Angle as champ will be good for business right now, since it will get Angle (and TNA, by proxy) a little attention. Angle can start his new "reality show" (is that still the plan?) after losing the belt, and can say that he was the TNA Heavyweight Champion in 2012. Angle would also be able to say that he beat Sting "cleanly", as that seems to be the major focal-point of this match (at least from the storyline POV). I know the Title is also at stake, but you know what I mean....
I might be looking too far ahead here, but I don't think the belt will immediately go back to Sting (if Angle is the victor at HC Justice). I bet they'll have a rematch (presumably at the next PPV), with Angle winning that as well. I think TNA would be smarter to have Angle eventually lose the belt to a younger guy, putting that "young guy" over with the audience (once Angle is ready to leave, to focus on the Olympics). That's just plain good business.
Again, I'm probably looking too far into the future (we don't even know if Kurt will beat Sting for the belt yet)...but I can see Angle losing to an up-and-comer (ie: Crimson, Gunner, etc), or possibly even Mr. Anderson. Sting has had more than enough time with the belt this year, and I believe it's time to pass the torch.
I hope Sting will become Champion again in the future (if he loses the belt this Sunday), he's still got a little time before he hangs up the boots for good. Who knows what will happen with Kurt? In his mind, he might be leaving TNA for good - when he leaves for his Olympic Training (& Reality Show)...I mean, he could retire, he could suffer a career-ending injury, he could go back to WWE, or could wind up on Impact again. I think putting the belt on Angle this Sunday would be best for all those involved...it could be the very last chance Angle has to hold the Strap.
