<I actually did the same scenario here.   I have a full size 40M dipole at 115 feet and I fabbed a vertical full size dipole for 40M and hung it from the side of the tower for comaprison.   On DX the vertical won hands down on every sig.   On closer in, stateside <stuff stuff the horizontal dipole was the best.  Not suprising, the vertical dipole has a lower angle of radiation.   I also checked to be sure the tower wasn't interacting with the vertical dipole to be sure it didn't screw up th pattern.  I am very pleased with the <vertical dipole's performance (for DX)

##  What did you make the  40m  full sized dipole  from, wire..or  tubing ?   How far is it spaced away from the  tower ?  How high is the dipole on the tower ?   Is the  top of the aprx  66  ft  dipole  close to the top of the tower ? 
My guess is,  the tower is acting like a reflector  behind the 40m  vert  dipole.   IF that was the case, you would see  some amount of  FB in the opposite direction..and some  FS.
