Lando, Wedge, Biggs, STH, Boba.
Lando or Wedge lead (L).
Lando, if you need the speed. Look at your opponent's STH and Boba (if existing ofc) before you fight them (stats field at the opponent's hero) and know your own stats.
If the opponent's Boba or (!) STH are faster, choose Lando. Ofc you need to take into account whether the enemy uses Lando lead himself and add the respective value (e.g. 13).
Otherwise Wedge.
If you are slower even with Lando, you will probably lose the fight. If you are not so lucky to be able to execute enemy's Boba.
