toby it depends on the tree but first thing you do after getting your safety strap tight get your bow and do a whole bunch of practice draws in every direction so you can get an idea what shot to wait for if a deer comes through,,,, I already know I have a few angles I can't really make so I just avoid that shot and wait for a better shot if something shows up.
but its not a bad idea to have the shortest bow you can shoot on the rack with the others for those times when the 66's bottom limb is just too long for that stand.
