Change of Hunting Tactics

Ok thanks for the advice. I wont be able to hunt until monday due to work. Part of being a firefighter I guess, gotta work the holidays. So I wont be able to really mess with them in the woods till then. Although I have been riding my dogs on the dog box to work with me for the last two days. One of them (the less experienced one) is riding fine and has his nose up the whole time. The other which is my main dog kinda hunches down and holds his head down the whole time. Im gonna keep riding him up there to see if he gets used to it. Still got a couple more who need to be ridden on the dog box to get used to it. In yalls experience what are some advantages and disadvantages to rigging? And thanks again!
