Thanks for the quick info already guys!
For scenes, we're looking at 6-12 sq-in, so we don't need a large area of light, which helps! At the higher speeds, we're also looking at events that create some light themselves (namely muzzle flashes, gasses going through compensators, etc.), so we have gotten by with mostly black backgrounds and picking up the bits of light which are more important to us.
Buy-charge-click on is preffered, and I didn't notice that the one Godox light in the Chronos was battery powered the first time I looked! But we're cheap, um, I mean efficient with our money use...
The Stratus "mount on a board, attach a battery, plug in a switch and a pot" get up is about as "DIY" as we'd want to get, and that actually looks pretty good... I might go that route if nothing easier/cost effective comes about...
Thanks for your help guys!
