I have one and used it for a few years. 180-240. Really liked it and very stiff. It broke in the middle of one arm where it tapers. Sleeved and wrapped in carbon and now stronger than before. I suspect it damaged during travel, hard to say. Great booms, a touch on the heavy side. The only other thing, mine is probably 6 years old and the clamp at the front is not as easy to put on as it should. The latest ones are better. Good grip compared to NP. I was happy with the Naish carbon boom
