Best title for mental toughness for a competitive athlete


I am hoping to convince my nephew to run a subliminal. He is a tennis player and is one of the best in the state where he lives. He dominates players who play at a lower level of skill but often finds himself getting nervous and playing inconsistently when playing opponents equal or better.

I am figuring Spartan would be the best title to run for the development of an athlete’s mental toughness but would consider that a title like Ascension or even Emperor might be as good or better.

Would most like to hear the thoughts of Saint and Fire.
