I have two stands I use,one tree stand like I hunt from,then one that is only 10' just to use to be able to set in it like my reg. tree.
then I also shoot from a chair on the ground, in case I use my blind.I shoot from all positions,setting , standing,turned around???just as sure as you don't, thats the way he will come from.

I shoot several times each day for a few weeks befor the season just to be sure its the same every shot.my wife shoots 5 shots a day.she can't pull the bolts out so she has to wait till I get home.

if you don't shoot from a tree, you will not get the feel of what may happen.
