If you are bonding your coax shields at the bottom of the tower, would it be better to put the choke on the shack side of that bond, or on the tower side?

On the shack side.  In general, coax on a tower should be bonded top and 
bottom.

Well, at least "suggested" to ground. :)  But the inductance of the run 
to the shack does that too.


There should, of course, be a choke at every antenna feedpoint.
