No shame in using a bucket or crane in my opinion. Heck, you'd be a fool not to if you had the money and wherewithal to operate that big.
There is always going to be the need for technical climbers to get where the bucket won't reach but sometimes a bucket, lift or crane makes so much more sense.Like when you have lots of trees to prune on a location or multiple locations (like after a storm). Hey, I consider myself a pretty fast climber and an excellent manager. I can work two climbing crews to death and climb as well but I still ain't beating the bucket crews.
Also, when you have 3 30K trees in the back yard and can pick them over the house to the street are you going to tell me it makes more sense to rope everything and have to carry 90 thousand plus pounds of tree to the front? I had a guy bust on me here on this site a year or so back about talking up the crane so much. Said he could do more than I could with the GRCS for cheaper. Hogwash! The guy we did that job for didn't want a bunch of tree guys camped out at his house for a week while he hoped they didn't drop something through his roof. He wanted the job done now, with a crane and had the money to pay for it. We had like 14 hours into that job. Only 10 hours climbing for me and I was setting at the house drinking a cold beer counting thousands while Mr. boat winch would have still been humping for 3 or 4 more days. Don't get me wrong, the GRCS is an awesome tool but it's no crane.
In every town your gonna have the older guy who has paid his dues and has all the toys to play with. He'll be the old crotchety bastard who is naming his own price. I have a lot of respect for that guy. I've learned a lot from a few of them and hope to be where they are at someday myself.
What I don't like is they guy who borrowed money to buy a bucket and jumped in there with no knowledge of what tree work is about. You know the guy, the one who is running down the road hat racking every large hardwood on every Elm street in America.
