RE: Sit or Stand?
First let me state I hunt where herds come through and they can show up all the time. I believe in the fact that they eat every 4 hours.
Like others have said I always stand first and last hour. To save my arm the weight of the bow, I hunt with an Oneida. The bottom limb slips comfortably into my front pocket if I want to be in the ready to shoot a deer. I put it in my lower leg pocket if i want to be at a rest position. That allows me to cross my hands over the upper bow and keep them warm. I hate wearing gloves. I still can slip to the ready very easily or sit back down with the bow still in the leg pocket. I hate my bibs because they don't have that pocket and I have been thinking about adding one.
Here is my advice on when and how to move. I believe you need to be high in a tree. The higher the better. Deer do look up. Nothing is worst to have a big boy coming in with litlle ones below bust you. Second, alwasy practice grunting in a buck even if you don't want to shoot him. This helps to you gain the effective range of your grunt, not to mention your technique. Last, don't be afraid to move 30,40 50+ yards if you see deer moving on another trail. This is a must if you see Does during the rut being chased by a few bucks. Chances are good another horny one will follow with in 30-50 mins. If you don't move you will just watch. Even if it's not during the rut, don't be afraid to move. You can slide down a tree and get up another one very qiutely if your good. You'll make no more noise then anything else in the woods but you won't just watch them walk buy.
Good luck
