Ah, finally an answer to what Rumble match was the longest. Anyways, I'm still a bit shocked that it wasn't the longest, but it wasn't by much so I probably shouldn't be.
Personally, I'd rather have Rey versus Rhodes. They took Rhodes off the Rumble for this storyline, they should at least give him his Mania match against Rey. I suppose he could also be in Money in the Bank but that's just not the same. Especially since Rhodes seems to me like one of the guys who wouldn't really take the spotlight in that kind of match. He could prove me wrong, but I doubt it since I actually can't see him competing in MITB this year. So yeah, out of the two, I'm pulling for Rey vs. Rhodes.
