+1 to the two posts above. If architecture shooting is primary, there are better options than a ballhead. For the gear you mentioned, the Z1 is likely much heavier than you'd ever need. Perhaps a Markins Q10 or RRS BH40, if you feel a ballhead is what you really want. Also, since you mentioned your height, be very wary of extending the center column on any tripod, as stability will be easily compromised.
