Well with this set up we were running a total of 5 flashes. 3 on the back colums at 1/8th power zoomed to 85mm to keep a tight beam of light. It looks like our middle one was zoomed wider as the entire column is lit up. Oops! One flash in an umbrella at 1/4 power and one behind her for a rim light at 1/8th or 1/16th depending on the shot.
