you never answered his question
i have a nankai freecoaster hub and it works great. theres not much slack because i learned how to do mainainence on it by taking it apart and remembering how it went back together and greasing it. i barely have any slack, and its great. this 1/2 turn stuff is crap, i have never seen anyone who has 1/2 turn slack, so do not listen to "all mighty god of bikes" such as the previous reply has led you to believe. if you want a freecoaster hub, the second best is a nankai. the first is suntour coaster with an unbrake, but those are rare. so go with the nankai, it will never do you wrong as long as you take care of it. he is right though, keep practicing, youll get it.
