A proper candidate for Shliach Tzibur on Yomim Noraim and the
whole year, should be one who: 1) has no Aveiros (or who has
done Teshuva for them); 2) does not have a reputation for having
been a sinner when young (even if he did Teshuva then); 3) is
humble; 4) is acceptable to the Tzibur; 5) has a pleasant manner
and sweet voice; and 6) regularly reads TaNach. (MB 53:14-18)
