Had a (no2, or 2nd clamp down from top) clamp break yesterday & not sure if any other make will fit cos they're out of stock where they originally came from. Got the 30ft Elite carbon fibre pole from 'the water fed pole co' based in Northants I think (bought off Ebay) Would I just be best to replace ALL the clamps with a more robust set from another make? I notice Gardiner sell clamp kits as opposed to paying for separate clamps? Anything I should be looking for in terms of composition to ensure they really last this time? Thanks for any advice!
