I am with Murphy on this one...some of the guys on this forum DO know a whole lot more than I do or ever will. I appreciate the time Dan takes to put out these videos. Reading the comments of the pros about his videos is instructional in itself...Willie (SOTC) commented that he noticed a dutchman at 1:29...I went back and, sure enough, there it was. He saw something I did not and took the time to point it out. That in itself was instructional for me. Without Dan's video there would have not been any exchange of info.
People post videos for different reasons...and putting it out for others to see is inviting comment...some tactful, some helpful, some rude. But, just like the vids are posted for different reasons, folks can get different things from them. Some of the techniques are interesting to see done, some are new (to some of us with limited experience) and some may be dangerous. That is where I like to see where the pro fallers, loggers, arborists weigh in and give their input.
