I like to set up on the inside of the edge at a turn if possible.
I feel just the opposite about where to set up on a bend.
Think about this for a minute...
Draw a "U" for illustration purposes and put a dot in the middle of the U (North is up). (The U is a much exaggerated example of a turn but the general concept still applies). That dot in the middle of the "U" is your stand. The only wind direction that you could hunt that stand without odor blowing toward the trail is a consistent, stable, South wind. Being on the inside of a turn is more critical of slight shifts in wind direction.
Now, place the dot (your new stand)
underneath the U...about the only wind direction that will screw you is a South wind. Any wind from the N,E,or W will not blow over that trail. Even a WSW or ESE wind may miss any deer traveling that trail.
One belief about stands in the middle of the U is that deer tend to look straight ahead when approaching a bend so being in the middle has less chance of being seen. But with a saddle, we can keep the tree trunk in between the deer and us and chances are less that we will be visually busted. Being set up on the inside of the U has (slightly) less chance of being
visually busted but a much greater chance of an
odor bust. We can get away with a visual bust much more so than we can get away with an odor bust. A deer that
sees us may finally relax and think we are not a human. A deer that
smells us seldom relaxes. I will risk a visual bust over an odor bust any day.
One down side of the outside U stand is that a deer walking around the U presents less true broadside shot angles than when in the stand is in the middle of the U. The inside stand has the deer parallel to you for a greater period of travel. The outside U has the deer quartering
to us for a greater period of travel. Quartering-to angle shots should never be considered as an ethical bow shot.
Also...The outside U stand will tend to have deer, that are strung out along the trail, all above you and easier to monitor by you. A stand on the inside U may have strung-out deer on 3 sides of you at one time. Pretty hard to draw on a deer when you don't have eyes in the back of your head to see if deer are watching you.
That all being said...It isn't very often that I find a bend with suitable trees on both sides of the trail. Seems like more often than not, just finding ONE tree in the right spot is a challenge for me and my traditional equipment shooting range.
