I have had my KA Carbon slalom and wave booms for 2.5 years now. No issues, very stiff and sturdy. The reduced diameter of the wave boom is really nice for BnJ and wavesailing.
I've had my ka race and wave booms for around 10 years.
I've replaced the clamp head on the race boom once and the clips on both boom arms of both booms once.
Great booms.
I have one of their wide aluminium booms with pulleys in the back end that is quite old but still in one piece. Thinking to replace next summer.
Who sells KA product in Australian now?
