Public land I'll likely shoot whatever makes me feel good be it a spike or a booner. Its pretty much a waste of time to try to manage. At least on the lands I've hunted. As far as going from one property to the next I guess it all depends on the potential of the land. If I know there is a good deer population and my odds of shooting a better deer are good I'll likely pass the small guys. If I'm not likely to have anotrher shot opportunity all season I'll more than likely take the shot. I would have to get to know the land and then make the call.
