Most salespeople who have memorized, role-played, and practiced overcoming objections are big stars in sales meetings - until the other people find out how low their closing rates are.

Overcoming objections creates adversarial relationships. Adversarial relationships results in low closing rates.
Eliminating objections is easier and produces much better closing rates.
