Rinne sasuke is alot easier to get now, his frags are in more events, and he is alot better than killer bee. Killer bee is decent as pos 1 but not the best, and not really good at any other positions, especially without bt's. i would suggest getting rinne sasuke because you could replace asuma wb with another rinneg*er, for example like pain gakido who is a good support for rinne sasuke, and he is free which is really good, or you could use another akatsuki unit like konan for the buff, or even kakuzu for the heal.
