First question is does it need to be stock proof?
Does it need to be attractive?
The smartest and most stock proof is Midland, which is basically what you have done. It is also the most labour intensive and requires the most materials.
The simplest and requiring the least materials is what we do on the farm which is a poor imitation of Devon or Berkeley style. Pleached over , laid close to the ground and held in place with big bale string.(which will be removed next winter.
The stakes and binders are only there to hold the pleachers in place, make it more stock proof and attractive.
For a low hedge you could crook it like Devon style, higher you could just stake it as in some of the welsh styles.
