Since you're in IL, are you able to get to the meet at Buffalo Rock? I'm fairly certain you'd find at least one of the rifles you're considering.
If you can't get to that range or you're unable to find one to test fire, your only other option is to find a gunshop and handle one. Look, there's absolutely nothing wrong with asking questions. Besides reading books, how else can you learn? The problem is that after a while, you're going to get all the opinions you can possibly have. Asking questions to gain knowledge is good. Asking questions in seach of validation is not so good. I'm sorry but from reading all your posts, it seems like that's what you're looking for.
You started out choosing between an FAL and an AR. You solicited this board as well as the FAL board and got a lot of feedback. Towards the end of your original thread, you'd decided on a flattop AR. Okay, great. But then I saw your now deleted thread soliciting the pros and cons of flattop and non-flattop ARs. I thought "wait a minute. Didn't he already say he preferred flattops?"
What I'm trying to say is that you can ask a lot of questions and solicit a lot of opinions. But eventually you're the one that has to decide. No one here can guarantee you'll be happy with what they like. That's also why I suggest somehow getting an example of each in your hands, if not to shoot, then at least to feel it.
