I went to their training session in Charlotte a few years back. It was a group of 13 college instructors, sponsored by Vermeer, Husky, Bartlett, Sherrill and others. Some were beginners, some, like myself had 30+ years of bad habits, but all of us learned something we could use. Some of it I don't use myself on the job, but I have shown the techniques to students and some of them have told me how great they work. The more tricks you know to make the work easier and safer, the better the chance you have of tweaking your regular techniques when the occassion to do so occurs.
I think enough of their training to make it an alternative to my own climbing class for the online programs I offer in Urban Forestry and Arboriculture.
