Hi,
Despite having a Nissin Di866 II I don't find I use it all that much and I'm thinking it may be down to the physical size.
When I'm out that I often use the 70-200 2.8 but for whatever reason seem to end up doing a lot of post production work to light the face, to me the obvious choice here is to use flash fill, especially as my kids move about ALOT!! That would be the reason for wanting HSS too.
Sadly a simple reflector is out of the question unless someone can figure out a way to tether it to the kids and keep it out of shot while they rush about like nutters 
Can you suggestion a good flash for this and also with the studio setup as a slave (to be mounted on YN 622C's)
Thanks.


If you can find a nice light wall next to a play area in the shade, this also may work, with some trial and error (and a white balance setting)
