^ Paul, the Quadras and the Ranger, are very commonly refered to, but as completely different units.
The quadras are the 400ws, the Rangers are the 1100ws, both battery operated, priced a bit differently.
This is just to avoid confusion if you shorten the Quadras to Ranger, everyone who follows Eli, would expect you to be talking about the 1100, regardless of context.
BH names the quadras "Ranger Quadra", so i can see where you take the shortening from, i'm just giving you a heads up from someone who follows Eli light discussions alot. I had to re-read your post a few times to confirm, hopefully its just me but you might want to be stay clear.
Personally, i think Eli made some confusing naming choices but oh well.
I am glad to hear about the mounting accessories, as for those mentioning options to the Quadras, there are quite a few Chinese offers, I'm sure at least some of them would be decent, or would end up being decent after a few more revisions ^ ^
Personally, i would love a Quadra system especially now that theres a ringflash involved, but AC monos are simply more adaptable/cheaper at the moment.
Also, the whole thing about on-location "weight" is somewhat empty to me because you need to sandbag everything anyways, so even if your flash is super light, you'll need to compensate with larger bags.... Clamping the Vagabond has always been a great solution to this.
