I find it a little difficult to call it a 'feud.' It is really just the build towards a match.
It's been okay so far but I am not entirely sure about putting Mundo and Drake against each other so soon - either your new champion or new top babyface has to lose, or you are relying on Creative having the subtly to have either lose and not lose steam (something I have very little trust in for TNA or WWE, except nXt) or some kind of hopefully non-groan inducing Dusty finish.
I would have been tempted to keep Mundo out of the title picture for a while at least. Have him take out LAX and then have to deal with the inevitable heel turn of Alberto.
Drake could have had a couple of matches with Eddie Edwards and something short term with Sydal.
