I've got to say the RC1 remix is really starting to grow on me, I was humming it in my truck today!!
Leathered, I'll be honest, it sounds better with the guitars than the pianos, those piano samples just don't have the range for what you want to do with them.
I prefer V7 if i'm perfectly honest.
I'm still at a loss as to which one i'm going to use in the intro, i'm leaning toward the RC1 remix, but size wise, it might be better to put the burningbridges one in there.
