Been using the pole for about a week i suppose and love it but couldn't get on with the clamps that well, i found them too stiff - loosen them off and they don't grip the pole. So, over the weekend i was fiddling about and squirted a small amount of silicone spray onto the plastic inserts that the cams run on. Then i lubricated the metal rod bit that sits in the lever with a tiny drop of wd40 and hey presto! the clamps are great, easy to use to the extent that i forget all about them now. The perfect package.
