If "Rigging for Removal" is the speedline video taht the NAA put out, I would say it is only OK.
The latest series from the ISA is a better value.
"The Art and Science of Practical Rigging" ASPR'n...aspirin...
The workbook is really good too.
Dr. Pete Donzelli wrote the original draft for the series. This is a really complete session on rigging. If you aren't an ISA member, you might save almost the membership fee by joining.
In November of 2000 I took a week off and worked on the video with General Sharon Lilly. I was a Best Boy for the production. That means I did Sharon's go-fer work. On one day I did get to climb and tape Sean Gere while he was doing a limb removal. About ten seconds of what I taped actually made it into the video. The week was a load of fun. I'm glad that my boss understands when I need to take time off without pay
