Looks like to get HSS or hypersync to work it is either through the ttl protocol, or optically see the flash pre sync. You cant do that from the center pin trigger signal. The camera needs to think it has an HSS flash on camera. The RF60 will see the pre signal then go into HSS pulse mode. So right now the only option is optically, which both the RF60 and V6 have. I am going to do further testing today, although its not the most idea situation if your only focus is HSS. However its cheaper than buying 400$ flashes. I am going to do some more testing today. What type of camera do you have?

I understand getting HSS via optical mode but above you also said thru ttl protocol?  Please explain.

I use 7D and 5Dm3 cameras.
