I love power, but I love saving money too. I want to get two 800s. This is what I want to do. I want to be able to over power the sun and light groups for wedding shots. How many people will two 800's light up. I really don't want to spend more money on the 1600's so can anyone give me a reason why you had to have them or thought about considering them. I'll probably shoot through softboxes alot. I'm not sure if that deminishes your power or not so that is a concern. Thanks in advance.
