I use Inon strobes with an Olympus camera and fiber optic cables. I use TTL almost exclusively when shooting macro and it rarely fails to do exactly as expected. When shooting wide angle results with TTL are less consistent and I'll switch to manual. The difference for me is due to the fact that macro images are 100% illuminated by the strobe whereas with wide angle I'm working to balance ambient light.
