If a guy has 3 vehicles, a station wagon, a pick-up, and a dump truck, all in good working condition, insured and dependable, and he needs to deliver 5 cords of firewood to a client. If he chooses the car, I have to wonder about this guy. How many other stupid things does he do during the day?
If you see a guy delivering firewood in a station wagon, what genralizations do you make about him? I'd think he probably isn't a pro.
But... we shouldn't make genralizations. He may be the top firewood producer in the nation, I doubt it though.
Similarally, when I see a guy climbing on a tautline hitch, I think he's old school. He's not up on better and easier ways to climb, and it's a good bet that he's also not up on better ways to do other things. He most likely guts, lions tails, and tops. He doesn't know much about tree biology, insect or disease problems either. He doesn't belong to the ISA, or attend trade conferences. He spends very little time, if any, outside regular working hours, trying improve his craft.
It's also a safe bet that he doesn't concern himself too much with safety or safety gear. He's a hazard to himself and others around him.
In spite of this, he's been around doing this for years, and has convinced himself that this fact alone makes his workmanship good. In fact, he thinks he is one of the best climbers in his area, pehaps even the world. And why wouldn't he? He's the only one he's seen climb.
A climbing hitch is a key tool for a climbing arborist, like a dump truck to a firewood delivery man, it is the most often used tool he has.
What if you were considering hiring a logger and his first statement at the interview was that he has a really long extension cord for his saw. Like you, I'd wonder if he knew anything about logging. Does that one statement alone definately mean he's not a good logger? I guess not...
