Default dipole extension?

Hoping someone might have a idea as to what's best in this situation...


My set up

a sgc237 tuner at bottom of a (center support) 5' pvc mast, feeding 5'
450ohm ladder line to a horizontal center fd dipole


Issue:
unfortunately i don 't have too much horizantal roof space seems i'll
have about 40ft on one side maybe 20ft on the other

the ends will be supported by tv mast and clamped onto the sewer (cast
iron?) vent pipe on each far end

The far end masts are 10ft tall (making entire dipole 20ft off roof
surface)

3 questions:

a) would it be better just to leave the dipole as is horizonal(and
kinda short for multiband dreams) or

b) extend it by adding a 10ft verticle wire along the mast (using
plastic spacers?)drooping down

c)attach my dipole to the mast making it part of the dipole (this
presumes the cast iron sewer pipe makes too poor a connection to matter
i don't know , suppose i can rap it w/duct tape)
