Which Farmstokk Solar Fencer?

I have a mains fencer but it's not reaching the top of the field, so I thoght two zones might be best. What would you like for 3-4 acres on three sides, one line of wire. There's a boundary, it's to keep them off the trees and bushes tearing themselves to bits! Thanks,

I have several Gallagher S20's for fencing the sheep away from home.
