TL;DR.Essentially a tie — LoRA at 50% barely edges plain BASE (0.503 vs 0.499), and the evolved steering prompt actually lowers reward (0.470), so use a neutral prompt with at most a 50% merge. Emotion strength stays tiny at 50% (emo 0.008); pushing to 150% raises emo to 0.109 but craters blend to 0.155 and reward to 0.364. The tell-tale side-effect: at high merge teasing collapses into overt Amusement (shift +2.02) — it becomes laughter, not sly teasing. Across all levels teasing shares acoustic space with Sourness/Anger/Contempt (corr ~0.9), so it can read as mocking; keep the merge low and let playful wording set the tone.
Without a LoRA
Best: neutral prompt, no LoRA → reward 0.50
GENERAL: A voice to the extreme expressing teasing, a playful, teasing voice, sing-song and mischievous, poking fun, pouring out.
