I am sailing with adjustable diamond tension on my Blade and the times i did sail it now i changes constantly the tension when it is needed special up wind. The problem is that you don't have enough hands to change it down wind. On my boat it is possible to change the diamond tension from trapeze so i am flexibel when i am going up wind. I found out that the alu mast is responding more dramatically on the diamond wire tension than the carbon mast i am using on my A class and the reason for this is , is that the alu mast is not that close in stifness in compare to the carbon mast A mast.
The exact set up on how to handle in sudden wind conditions i still have to find out for the alu mast. There is some sailing needed this winter.

Hans
