Using for example many of the scritpures and logical reasonings in "In Search of Christian Freedom" by Ray Franz will allways give you the appearance of someone who is in search of Bible truth, rather than somebody looking for an excuse. Whether you are really interested in the Bible is you own decision, but I feel that by using it wisely and with skill you will allways have the upper hand over the Elders.

Uhhhhhh...been there, done that. You never get the upper hand over the elders. Up until the early 80's, you could intelligently discuss scripture....but up to a point. Now you cannot discuss scripture unless it falls within the parameters established by the Society. For example, you gave Matthew 20:1-16 as an example of a scripture you might be "concerned about" with the accompanying question, "How then is it that only people born before a certain date will go to heaven?"
If you asked an elder that question 25 years ago, he would tell you to do some research in the Society's publications, and if you still weren't satisfied with the results, then you could write to Bethel directly and ask them. If you ask an elder that question NOW (and you're no longer a newbie JW), you will be put on a short list of people in need of watching (maybe a long list depending on the amount of dissonance in the congregation). Merely by asking that question invites closer scrutiny because you are still expressing concern, albeit scripturally, about a MAJOR doctrine of the JW's --- the 2 classes of individuals in the organization (anointed and other sheep) and the "carved in stone" date (1935) marking the time of their distinction. If the elders are "nice" about it, they'll "kindly" direct you to Chapter 97 of The Greatest Man Who Ever Lived" book for the "proper" application of that scriptural text.
As the October 1, 1994 Watchtower states at the bottom of page 8, "All who want to understand the Bible should appreciate that the 'greatly diversified wisdom of God' can become known only through Jehovah's channel of communication, the faithful and discreet slave. ---John 6:68."
