First of all, let me say that I'm thoroughly enjoying my Cactus RF60 flash and V6 Trigger. I'm a Nikon user and I also own the SB-700 flash which has TTL HSS built in. The documentation doesn't really explain how to use the HSS Sympathy mode on the RF60 flash. Can someone explain in detail or step by step how to setup and use them in this manner? I have some photo ideas that may need me to use this feature but I'm at a real loss at this moment.
