Don't cut the back hide!
Cut around each leg at the knee/elbow. Zip to the belly centerline. Zip open the belly/chest hide. Skin the top side all the way to the center of the spine or more. Fold open the hide as clean as possible. Pop the quarters off and hang. Feel free to land on the hide if needed. Grab the neck and straps.....now roll and repeat. Now that you have a stripped carcass with guts in it still, push the guts back so you can tickle out the t loins.
This whole process will take you an hour. You can bone the quaters now that you have the hips cooling.
