Should have good hunt with 5 points if you do your homework! I hunted a 4-5 point unit with a buddy this past year and found a couple 190 class deer in the first two days. If my buddy could shoot, I could show you a picture.

I have hunted it three times in < than 5 pt units and always see 180" plus bucks. Not always killable, but you see them. We always have harvest opportunities at 160" and 170" class deer in those type units, though.
Here is a little hint - If you are hunting the 3rd season, don't worry about showing up opening day. It is much more important to be able to hunt through the last two days than to be there for the opener.
