[SI-LIST] fields question

hi,
it's a simple question:
i have a PCB with several line e.g. :



 
----------------------------------------------------------------------------
----------------------------------------------------------------------------
- Z = 14.8mil   
*                                 /////// up power Plane ///////////

*
----------------------------------------------------------------------------
---------------------------------------------------------------------------
Z = 14.1mil
*                                       Er = 4.2   H = 13.4mil
*
*    bus1        bus2   bus3    bus4    bus5    bus6    bus7    bus8    bus9
bus10   bus11   bus12
*    XXXXX      XXXXX    XXXXX  XXXXX   XXXXX   XXXXX   XXXXX   XXXXX
XXXXX   XXXXX   XXXXX   XXXXX           z=9.4mil
*
*
*
 
----------------------------------------------------------------------------
----------------------------------------------------------------------------
- Z = 0.7mil
*                               //// Bottom power Plane ///////////
*
----------------------------------------------------------------------------
---------------------------------------------------------------------------
Z = 0


all the lines are identical. let's assume the outer lines (bus1 and bus12)
have infinite space from the edge of the PCB. i want to put one line tied to
the ground (or VDD) while the others are toggled between +50mv to -50mv they
are toggled together. my question is where will this line suffer more from
mutual inductance, if it will be placed on the side (bus1 or bus12) or if it
will place in the middle (bus6 or bus7)?
