I used the one I use for target practice last year.The legs and head fit inside the body,so it does not take up much room.You can make it a 6 point buck or a doe.
Your right about trying to set it up so the deer have to walk by you before they enter the field.They check it out really well before they dare come closer.I put a rwal tail on the deer and used fishing line to move it every now and then.
I had it set up as a doe last year and harvested a nice doe.This year I'm going to put the rack on and grunt and bang some antlers together.
ONLY USE IT DURING ARCHERY SEASON.
