Nick,
I like your set up.. Plenty of cover behind you. How do you expect the deer to come? Left to right head on or broadside? From behind quartering away (when the wind allows the blind set this way) is DEADLY on deer... If all works out next week I have a ground blind set in this exact situation. It all depends on the wind direction...
I would choose a "lower" seat. The bucket will have you to high and too easy for deer to catch your movement. I've used a Niff T Seat (without any of the height tubes) for years with superb results. I practice shooting my bow sitting on this seat as well. I have found the lower I can get the better.
Let the deer pass PAST you, draw slow and you will get them killed...! Ground hunting is a bunch of fun.
