sweetgum,
welcome to ASite!!
I also have taken the same three modules. Very good training. In our classes, most of the trainees were beginning to intermediate climbers. The instruction is very good for them, as well, for more advanced folks. Going over basics never hurt anyone!! And there is a lot of good advanced/ progressive stuff too.
The more advanced modules are even better, I've heard. I've seen some of Duane's ( Arbo Canada boss)pics and videos, very good...
For a well advanced climber, the appx $900 fee might be a bit steep. The Arbormaster training series videos are very good, perhaps an option. As well, there is so much knowledge out there these days, in books, Arbo mags, TCC's, and all the webboard interctions.
Thanks to Paul Sisson's efforts with a state agency, we got our fees reduced to $300. Paul is the two time winner of the AM Skills competition. It seems the event is no longer held, oh well....I'd have had a hard time being competitive, as some of my old habits are rather ingrained...
I learned this move there:
