I used the 25 setup. Let me tell you this, it is much superior for angling my shots. Now, when I hit the stick to the right or left, it does not do drop shots 90% of the time. Therefore, the 25 setup is good for that.
However, when comes to movement, I find that the following three things happens:
1) When the opponent returns the ball early, the joystick does not recognize the ball at all (no movement happens).
2) When the opponent returns the ball with a drop shot at net, the joystick refuses to respond (no movement happens).
3) When the player returns the ball with a drop shot behind the baseline, and the opponent happens to get it over with a return drop shot, the joystick does not respond (no movement happens).
When these three things do not occur, left to right movement, or vice versa is far more superior than any configuration that you have given me (this includes the improvement with angling)!
We have to just find a solution to those 3 problems (most of them are upward and downward movement I guess)!
I hope this helps,
