Except that when you feel that vibration you are already below ETL and what you are feeling is the vibration from the transverse flow effect. That's not a good technique, and certainly not when one can make a normal approach.
When making a steep approach that allows maintaining ETL if you are getting that vibration speed up just a bit as long as descent rate permits.
