Recently I have moved away from using the stylus. Re-ran the calibration using finger touch, and once you get used to the correct "weight" (and when to use the back of your fingernail) I have found it a much better way of using the scroll. Even clicking on small icons like the ones in this forum (new posts to left of thread topics) are more accurate with my big fat finger than the pointy stylus!
So ... do you finger ... or do you point!
