As to the stand itself, I want to be able to be tight againest the trunk of the tree. I feel unbalanced when I am stuck way out from the tree, not to mention exposed. I like to use the tree to hide behind also, and usually position my stand on the opposite side I think deer will approach from, and usually face the tree while I am hunting.
I like climbers because it keeps the deer guessing. Plus they are less expensive than having 15 ladder stands and 15 hang on stands (and frankly a heck of a lot less work!) They are also "theft proof" if you don't leave them in the woods or in the open bed of your truck.
I use a Summit Openshot, I love it. I had one of the orignal openshots and finally wore the seat out and upgraded to the Openshot Deluxe with the fold up seat. Its the grapes.
