Testing SEVEN Parallel Rails - What Do You Think?

For the upcoming 4th of July, I have an idea to try something new for the "backyard" show. It would be convenient if I could have 7 firing positions - spaced 20 ft apart, fired off one module.
So I set it up with 25ft cables between all 7 rails and modules. What do you think? Should I stay with the one module, or break it down to 2 modules ?
