Who Should Sheamus Choose?

Muffin Top Merkley says:

Out of the current champions, I’d prefer Sheamus vs Byran on the basis that I really enjoyed the previous matches between the two, and I can’t imagine that a Sheamus vs Bryan match at WrestleMania would disappoint.

That being said, I’d much prefer Sheamus using his Rumble spot to challenge The Undertaker. All Sheamus would have to do is cut a promo saying something like “I have already been a champion & I am young enough that I will have plenty of opportunity to be a champion again. But there is one thing that time is running out on & that is the career of The Undertaker. I want a chance to break the streak before the Deadman is unable to compete at WrestleMania.”
