You didn't say if this is a "Shepherding Visit" or a Judicial Committee or even just "two brothers sent to look into a matter."
To second what diamondiiz said (assuming you feel that you absolutely must meet with them), it's ok to admit to being DISCOURAGED and even to having DOUBTS. But be vague, don't say anything specifically that could in any way, shape or form be construed as apostasy. Always be vague.
For example:
- BAD: I no longer believe the WTBTS and the GB are really God's Organization
- GOOD: I find the changing doctrines somewhat confusing
- BAD: That stupid, new "overlapping generations" bullshit is a compete joke. Only a moron would accept that!
- GOOD: I'm discouraged that this system of things has continued for so long ...
- BAD: I think the WT leadership are all a bunch of hypocritical assholes that are completely out of touch with reality
- GOOD: I've seen some things that have gotten me disillusioned and discouraged ...
I don't know how old you are, but if you're over 40 or so you could add, "I was never even supposed to finish high school ..."
Depending on your personal makeup, don't be afraid to cry. This completely unnerves most JW men. They are for the most part very uncomfortable with it. It's good to make them uncomfortable.
I know many here push the DENY, DENY, DENY approach and I can certainly understand the practical benefits of dealing with things that way. But I tend to favor an approach that does not involve lying or deception because that is exactly what upsets me so much about this religion and its leaders. I don't think anyone should condemn duplicity and then be that same way themselves. But that's just me.
Another approach you might consider if pressed on potentially incriminating evidence is, "Thank you for your interest in me, but I prefer to keep personal things to myself." Then stick to your guns. Be nice, be firm, be polite, be unmovable on this point, "It's really none of your business."
I know because I learned the Hard Way from handling it incorrectly. I thought I could go to my fellow elders--men that had been my personal friends for over a decade--when I needed help. I was wrong, wrong, wrong!
Please learn from my mistake: The elders are NOT your friends. They are NOT going to help you, in spite of what you or they may think. If they are company men, and most are, they will follow the party line to the letter. The end result is generally not good unless one grovels in the most undignified manner. Even that requires a complete submission to following WT Rules and Regulations or at least the pretense of it. Bad choices both!
Overall, it's really better to not meet with them at all unless you think you will likely be disfellowshipped in absentia. If that's the case, then you might want to consider some alternate strategies. A lot depends on what's at stake in the outcome.
When I was an elder I always thought it was odd when people avoided meeting with us. Now I know better!
I'm hoping for the best for you. Please keep us posted,
Daniel
