Having been a strobist speedlight/alien bees light user I want to upgrade my game and learn how to use Profo lights. I plan on renting and trying them before dropping the cash to invest in the system. A friend of mine recommended I rent an Acute 1200 pack and some heads. Is the Profoto system easy to use without prioer knowledge? I know pocket wizards are built into them but can you any other triggers (i.e. Cybersyncs) via sync port to trigger them? Do all the heads work with every pack or certain ones? Anything else I should I know?
