I don't know about the Farmi, seems most people like them, and they seem to be the "standard". (around me "Farmi" is synonymous with tractor skidding winch, like Band-Aid or Kleenex is to...)
But I will say, when on the tractor I like sitting behind the protective cage of a Wallenstein when stretching the cable.
Looking on the internet, it seems some Farmi's have them, some don't?
I bought the Wally because dealer/location availability.
