Anonymous and Westie might well be right.
However… short of observing each tree climber in action there is no other consistent comparison to be made between climbers and their ability (withor without a chainsaw) - competition climber, working climber or both.
Human beings are lazy creatures by nature: if there is a list stating someone is the best, and the source of the list appears to be credible, this willbecome the yardstick by which quality is measured.
That's why 'Top' lists are so popular - universally. As far as we are aware there is nothing to suggest it will be any different in the arb industry regardlessof personal opinion.
