I gave tree-standing a limited trial. It's supposed to be the most effective, which I understand, but it's not very historical. Plus, unless you use a climbing stand ( really not historical ) I reckon you need a few stands around your hunting property to accomodate wind direction, time-of-day, etc. I also nodded-off once or twice up on my ladder - didn't like that at all !
I've "arranged" quite a few ground stands using whatever came to hand in the woods. It seems to work fine, and it's easy to set-up a few so you can chose the best one for current conditions. Then again I'm very fortunate in having the run of my neighbor's 200 acres - I've never hunted anywhere else yet.
I also Still Hunt quite a bit. Too antsy to stay on stand for a long time, I'm OK prowling slowly for a few hours straight. It also gives you an opportunity to scout and hunt simultaneously. But it's also easy to blow it and get upwind, or in sight, of your quarry without even realizing it. Seems like more work, but it's a traditional way to hunt. In backcountry skiing we call that approach "Earn your turns" - i.e.; ya gotta climb up the hill before you can ski down it !
