I suggest that the 'contradiction' is one of driving style rather than carb type. If your wiper is run from manifold suction inevitably this can go down as well as up. In general 'cruising' on level ground any throttle will be almost shut.
It is worth considering that the optimal place to locate a take-off for wipers may not be the same as for a vacuum advance distributor. I believe the latter are positioned to avoid unnecessary advance when idling at traffic lights.
Bill, have you considered simply tapping into the manifold?
