Just a point re. mixing auto-brake and reverse thrust on carbon brakes - if reverse is used at anything above idle it can lead to excessive brake wear. Auto-brake looks at total retardation values and, if reverse is effective, it will modulate the brakes to maintain the selected rate. Modulating carbon brakes leads to extra wear - they're better on single application held on, to get the temperature up and keep it stable. For carbons, medium auto-brake with idle reverse seems to give the best results - assuming no runway limitations, of course!!
