Thanks David, I went to the Website. It looks to me like you are talking about the 1.2m fixed carbon pole for the extension.
I like the idea of an extension, not only for further reach, but I think it would be harder to amputate one's fingers. I see they have some sort of protective gloves to prevent amputation, but I like the idea of a pole extension better. Like you, a 4' extension would be too long for me. Can I ask how were you able to remove the top end piece on the pole in order to shorten the pole?
