I would rather own two balanced lights with control capabilities, I e turn one down to 1/2 power and one to 1/4 power. than two different ones. That way I know I can balance them.

A big box is very useful and since you have the small (42") umbrella, I wouldn't send the big box back, just yet. I do like black backed umbrellas way more than shoot through style, but sometimes they are the only thing that will work, so I have the convertable type that do both.
