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?
