For any Pro's working out on the field, I highly, strongly recommend an FM radio/headset. The LCO is near impossible to hear in places, however it's broadcast on an FM station.
If you're following the light, you'll be on the field in the morning/noon between the banks, and moving the the right side of the flight line as the day goes on. This can make getting the away cells difficult unless you give up on the perfect shots on the right bank. By late afternoon you'll be on the flightline.
