with a one way or a spool. you will be able not only give you more turning but it will let you run more speed through out the turn. the only disadvantge to a one way you lose a lot of breaking. I just went back to spool and remember why I like it so much more over a reg diff. It also depends on what car your running. From what I read each car has a different characteristic, on each application that is used. I hope this helps. (OH if I someone noticed that I got this all wrong please corrected me.
