I think that as long I don't break, the greater the pressure, the better I can garantee that I can do something.
But one problem is exactlly that; as only I can garantee that I can do something and not what is exectlly necessary at the moment, I'm aware that i don't always do as good as I should or would like to.
But, so far, that kept me going and I intend to use it's driving force to take the Land Rover all way up the hill!
