A Tirfor is as powerful as any of them - a bit slower though!!
I have an awesome winch on my 110 - it is 300hp!!! Driven directly off the engine - a Capstan winch that means I can use miles of rope if I want.
The coastguard USED to use these all the time for cliff rescue. But then they decided it was unfair competition as they were forced to buy Land Rovers as they can't be fitted to Jap vehicles.
So they now use a portable capstan winch that is nowhere near as good so they can buy Jap 4x4s - they seem to foget that it is the British tax payer that keeps them going - not Japanese ones.............
