Based on the fact that you already have a preference, it sounds like you've answered your own question.

You posted your property for a reason. Don't compromise your decision by trying to be a nice guy. What benefit would you gain by letting these guys hunt on your property? And how will you be able to accurately monitor them while they are hunting? In order for them to be allowed onto your property and to abide by your rules, you're looking at far more time & work than I believe you have or want.

Just my opinion, but I'd leave the property posted as is. Save the deer for the enjoyment of you, your family, and those close friends you know you can trust and believe in your hunting prcatices.
