RE: BEST LAYOUT??????
I have the Avery Power Hunter. It's not what you want though. A great blind, but not comfortable and it doesn't have room for a dog door.
Hunter to Hunter secret: Get a kindergarten or exercise mat to set either in the floor of your blind or underneath it between the ground and the blind. This provides extra padding and warmth, plus they roll/fold flat so you can carry them in your blind in and out of the field. They are cheaper than the Avery or other brands cabelas sells.
