This thread could go 100 pages about antler restrictions and whether they work etc but for the most part all your club members have to get on the same page because if not you are spinning your wheels. If some want it to be a 'trophy' club, some want to see deer everytime they go, some just want some meat and will shoot every legal buck they see, then you are not on the same page and will ultimately lose sleep over it and thats not what its all about its supposed to be fun. I have family members that if there were 10,000 does standing in a field they will shoot the one buck (spike, 3 pt, whatever) before they shoot a doe

That gets old but they ain't changing their mindset and I would imagine with 33 members in a club there are some people that aren't changing as well.
In general, the deer herd (both health and size) are tied directly to the soil. More fertile the soil the more deer you can support and the bigger they get. Typically piney woods are not fertile soils so you have to come to terms with the fact you are not going to consistently kill the amount of big bucks like places along the MS River unless you high fence it and spend a ton of money supplementing them.
As far as mistakes go people do make them because in most instances you only have a second or two to make a decision whether or not you are going to shoot a certain deer (they usually don't come out in broad daylight and stand there under a feeder or food plot and let you look at them from all angles), BUT if the mistakes seem to be not really a mistake then you got to get rid of those folks or you are going to lose more sleep.
If I owned my own place I would do something like Specktator suggested - shoot it if you are going to put it on the wall and let the kids or newbies shoot whatever they want. Its supposed to enjoyable, not stressful
