Eric,
If I draw a line between the towers, it would point northease/southwest. As it turns out, I'm backing out of this problem. There are too many people with far too high pay grades causing too much heat who do too little for me to want to continue with this.
Thank you for the help.

But with a single wire that is long enough for the lowest band and a tuner, the higher bands are going to have lobes other than just broadside to the wire (could be a good thing though). Nevertheless, I'd strongly recommend against the traps if at all possible.
