I currently have a 90' grounded tower with a 6 el tribander on a mast at around 
105' and a 4 el 40m yagi at 90'.  I was wondering what you guys would recommend 
for building my first 160m TX antenna- shunt-feeding the tower or handing a 
T-vertical between the tower and a tree.

I have never model an antenna before and thus have no idea what the electrical 
length of the tower is. Furthermore, I plan on adding 2 more tribanders next 
year, at 68' and 30' so the loading will change. Finally, all the books I have 
read on shunt-feeding a tower have created an impression that doing so is not 
as trivial and certainly not plug-and-play.  Thus, I am considering the much 
simpler and more predictable T-vertical.

Your thoughts will be greatly appreciated.
