Stone- depends on the camera and strobes. Some Hasselblads were capable of TTL/OTF flash metering with dedicated strobes like the Hasselblad flash, various Metz flashes, and some Broncolor power packs could be operated TTL. I doubt though that the PocketWizards were ever made to connect those two systems as it would have been a pretty esoteric bit of kit with very low sales volume.
