[BC] FM bays

[Mglin at aol.com]

Well some of you know the best answer for this.  Your help is  appreciated.
 
Here is the question.  I am upgrading my FM  C3  25 KW  ERP  245'AGL, moving 
to 328' AGL
Currently using OMB 6 bay with 9.5 KW TPO.  Bays are .75 spaced
 
I have received three different recommendations from people I trust.
 
#1  reduce the number of bays to 3 and increase TPO to 20KW
#2  stay at 6 bays and install a new antenna
#3  increase to 8 bays and reduce TPO more.
 
My target cities are 13-15 miles from the tower site and the terrain is  
relatively flat.
