Thanks for the comments fellas.
Agree with Nino that finding the right mix is part of the fun, I probably spend way too much time on that though!
Cactus Canyon done today.
As before,
First group = Flash on, All lights on
Second group = Flash on, GI only
Third group = Flash off, All lights on
Fourth group = Flash off, GI only
May do TZ in the next day or so, little bit Led'd out.......
