Greg- I didn't do armorer's college but I was there for coaches college during the first two weeks this year. The armorer's (especially the first week) spent all of their time (and I mean all of their time, Dan DeChaine needed at times to abandon them just so that he could get some sleep, they were just THAT wound up about continuing) playing with Dan's collection of examples of equipment from around the world.
You basically learn what every piece of equipment from every manufacturer looks like and how to repair it, as well as what is crap and needs to be avoided and what the best of each part type is. You learn what the insides of more types of reels than you knew existed look like. You get to hear Dan's stories from in the trenches at international events from the past 40 (or whatever) years.
The first week they had 7 participants, the second had only 2, the third had 2 scheduled, although some more might have done it. From my observations it seemed to get a much better group dynamic when there were more people involved. While the two people in the second week very clearly enjoyed the course the first week people fed off each other and got more actively involved.
I'd definitely recommend the whole coaches college program, whether for coaches or for armorers. It's well run and is a great opportunity.
