DA ROCK,
Thanks for the reply. In my early days of flying, I let other more experienced pilots do my maiden flights. Sometimes, they were not successful and therefore, I got not time on the sticks. Now, I go out to the field very early before anyone gets there and perform my own maiden flights.

Here is a closeup photo of the stabilizer. As you can see, there is very little difference between the upper and lower curvatures on the stabilizer. It will probably not make any difference in the flight characteristics (but you never no). As you said, it depends on how effective the stabilizer performs on this model.
