A clic stripbox would be great for A flashes.
As a professionnel portrait photographer, I often work on location and try to have the lightest gear as possible.
For this reason I use a A flash as a backlight on the hair of my models and a B10 as my main light for their face.
And what is the most useful modifier for a backlight like this ? A stripbox ! So when I saw your clic system I immediatly felt that a stripbox would be the ferfect match for my kind of set up.
