Hello, Thought I would bring this up for discussion as these heads seem to have allot to offer and bring features and quality of Brons flagship Scoro at a very affordable price. They are available in 400ws and 800ws with the option of pocket Wizard trigger or proprietary RF S 2.1 system for triggers. Broncolor has also developed a new wireless (for iPad, iPhone) app to control all your Wi-Fi model Siros heads called Broncontrol. Seems to be a nice full feature app. Take a look at the link below for more info. Im interested in your thoughts and comments.
