Using a few degrees bank into the operating engine is good. Once single engine climb speed and clean center the ball. One of our very good pilots at our airline was taking off with the FO flying in a B727 and just before V1 the #3 reverser deployed half way because of a failure and the FO continued. The captain took over and used the 5 degree bank procedure barely climbing at 500 fpm. No reverser lights were on but he found by reducing power on #3 engine his climb improved. He was able to return and land and found the right side of the clam shell reverser had broken and went into reverse.
This is a fine example of how automation would have doomed them but basic piloting skills worked. He was in my era of pilots that made it work no matter what.
