Points noted.
The video is mainly to show how well the clamps grip no matter how badly worn the pole section may become. A pole in normal day to day use would be extremely unlikely, even after years and years of abuse, to ever wear in one spot to this degree.
The Phantom range was designed to not wear from the start, this is a first in the water fed pole industry and is one of the main USP's of the Phantom. Having a softer material in the clamping mechanism greatly helps to minimise wear and tear and keep the pole sections as new as possible. With the added backup of incredible clamping power to stop section spin no matter how worn.
