Hi there,
Pitbull is really great, anyway I din't set up it at my boxing chars with so much love as I did it at my main char... But for starting here it is, perhaps a bit too small for you, but you can easiely increase the scale of them

Copy it to WoW\WTF\Account\[Accountname]\SavedVariables\

Only to start with (I know, when running Pitbull first time, all unit frames are centered in the screen xD)
