On a special Thursday night edition of ECW on Sci Fi, CM Punk will engage in a "Champion's Choice" encounter against a real-life monster of his choosing: Mark Henry or Big Daddy V.

As the Straightedge Champion prepares to make his (literally) huge choice, WWE.com assembled a pool of experts to aid in Punk's decision-making process.

Batista
I've had some of the most strenuous wars of my career against Mark Henry -- and I still have the scars to remind me of how dangerous he can be. His strength is indescribable. Pair that with his hostility and you have one of the most lethal competitors in WWE today.

Tommy Dreamer
Big Daddy V is very quick and has an amazing center of gravity. I have tried and it's near impossible to get him off his feet. The very few times I've actually seen him down, I've seen him get back up instantly, like an offensive or defensive lineman -- though he's also about 200 pounds heavier than the average lineman.

One of Big Daddy V's greatest feats is that he's always moving forward and he's almost impervious to any punishment.

Rey Mysterio
I can tell you from first-hand experience that facing Mark Henry is a guaranteed brutal experience, physically. He is the irresistible force and the immovable object. Stepping in the ring with a man that size, who is so powerful, is a threat to your career no matter who you are.

The Miz
Big Daddy V is 500 pounds; he's tall and massive and still maneuvers well. I've been on the opposite side of the ring from that monster and I can tell you that there's a good reason why WWE Superstars fear him.

Balls Mahoney
In ECW, I've seen a lot of dominant individuals come and go. Considering I've had wars with all of them -- and have scars all over my body to prove it -- I have to say that the immediate impact that Big Daddy V has had on ECW is unlike anyone else before.

Picture this mammoth "thing" -- and I'm saying "thing" -- coming at you with no regard for your safety, let alone its own. That's intimidating. Looking at what he's done to some of his opponents, that's just scary.

Big Daddy V is one of the most unstoppable guys I've seen in a long time. I don't think you can contain him.

Matt Striker
To compare Big Daddy V and Mark Henry would be negligent. Take a look at Big Daddy V; you've seen first-hand the destruction he's capable of. As for Mark Henry, everyone seems to forget he's the World's Strongest Man.

Basically, if you look at it, one of them alone is completely unstoppable. If you had that choice to stand in front of a moving Mac truck or to hurl yourself from the top of a building, what would you pick? Personally, I hope CM Punk chooses … wisely.
