Hi Will & Brian. Thanks for clarifying that. It's not fair when you are judged by comments, which were taken out of context.
Also: your achievments with an (I'm assuming) unmodified Big Shot blow my theories out of the water

The next chance I get I'm going to put my Big Shot to the test!
Coincidently, I had been thinking of doing the very same project here in Britain. I'm about to approach the Tree Register of the British Isles (TROBI) and ask permission to climb and measure the increasing number of contenders for Britain's (and therefore Northern Europe's) tallest tree. Almost all of these have never been climbed and have only been measured by laser clinometer - with inconsistent results.
I've yet to visit your website and am intrigued about how and why the media got involved. The story of the rivalry between the Scottish champion and its rival at Lake Vyrnwy, Wales, and the eventual remeasurement of the Scottish tree with lasers was the subject of a BBC TV documentary. How much more interesting would it be if I climbed these trees with a helmet camera to measure them and talked more about the history and ecology as I went? How would this actually help organisations such as TROBI and the Woodland Trust?
However, I am worried that sensationalising the climbing of these trees would lead to 'have-a-go' rock climbers etc. hacking their way up these trees and causing damage to them as well as themselves. What is your view on this?
