Retra LSD is a pain in the a.. with Inon Z330...because the pilot Led light is not centered. You always have an offset between the flash and the pilot light area. I recommend you the Snooty for Z330 (optical fibers are used to mix light before the optical part). 1000x better.

I've upgraded my oneuw strobes a few months ago in order to have HSS. It is only possible through electric cables (was confirmed by Luca, who mentioned having no intention to develop an optical solution).

Nothing on the Nauticam MWL-1 ?

You can also add a diffuser.
