@richard > The problem really is that of expectation vs. reality. The SX has a tiny platter as compared to the SZ, and with much less mass. Even if you were to adjust the tension on the jog (which you can't on the SX), you're still not going to get the same effect.
Consider using the backspin within the effects if you can't get the duration you expect from the platter.
