Goldminer, you're never going to get "any real, logical or intelligent answers" to a serious set of questions. You already know what will happen: at best you'll get a runaround followed by "wait on Jehovah"; at worst you'll be labeled an apostate and possibly be disfellowshipped.
Some years ago I was able to submit a list of hard questions to someone in Bethel. I had no idea who was supposed to answer them, but my JW parents used a personal connection to submit a list. After six months of hearing nothing, I asked my stepdad whether there had been any response. There had (why he didn't tell me will become obvious) and the response was that the guy said, "I won't answer these questions because some of them are the same as what apostates ask." So you can see the braindead, cultish mentality at work here. This Bethelite, by the way, turned out to be the editor-in-chief of Awake!
If you really want to go ahead and do this, I can give you a short list of impossible questions that will throw them for a loop. I'd also suggest that you set things up so that your wife can be a bystander during all the proceedings. If you do this, you should first have a little meeting with the guy who is supposed to answer your questions, have your wife watch, and then you read off the questions one by one and gauge their reactions. Only after this should you submit your written list. You should also somehow work in the idea that a discussion is what you want. The reason is that most peoples' experience is that if they get a response from the Society at all, it's a piece of bullshit that fails to answer your questions. If you respond to the bullshit and demand explicit answers, most likely you won't hear back at all. Of course, it might be that this guy will be familiar with some of the standard criticisms of the Watchtower, and if so, he's liable to immediately go into "apostate hunting" mode. If he submits the questions to the Society, he'll certainly get back instructions to view you as a likely apostate and to make sure that he's sure that you're not "spreading apostasy" or in any way a "spiritual danger" to the local congregation.
Just play it smart, man!
