Hey, hold my beer and watch this!
Having spent 25 years on 737-200's on short and gravel ops and 15 years on wide-bodies into a large variety of places (including PHOG in 787's ) don't count on anything being constant throughout the event. Use your brakes until they are ineffective (they will be in a reject from overheating when at 30 kts you think they might slow you so you let up) and use reverse to it's limit if in doubt.
Always have my hands on the reversers when approaching the gate.
Love to see the look on the opposite side breaking groups face when they use it to invoke a turn and when they hit a dry patch and it wasn't perfectly at max pedal.
Never hit a blade of grass yet.
