Besides the above recommendations I suggest also, after idle throttles, to use thrust reversers (F2).

Most RTO would be due to a engine out or acting up etc. In witch case you do NOT want to apply reverse thrust. Reason is to keep the plane going straight and not get lateral movement witch could make you lose control. Proper real life procedure last I checked on RTO.
