It seems everyone is having problems with the metal bars that are supposed to keep the rudders down.
I have the newer AHPC carbon stocks and kick-up system. They replaced the old glassfibre rod by a heavier on and I will go on record by saying that I'm quite happy with this setup. I sail of the beach and on the sea so typically I have a surf to get through when going out and coming back in. I found that you best do a few things differently but when doing so I'm more happy with this system than the ones I used on both Prindles and older Nacra. I also prefer it over the newer Hobie and Nacra systems in some conditions while in others prefering the newer Hobie and Nacra systems.
