I have a 2012 Phantom 320 and love the board. I had read about the problems with the sticking dagger and was initially concerned. I used one of the suggestions on the forum and applied carnauba car wax to the dagger and have had no difficulty with the dagger. I have not had to reapply the wax, but have used a spray lubricant in between sessions.
Hope this helps. This board has increased my sailing significantly and use it in my most common winds of 5-15 knots. Will switch to a short board for winds consistently greater.
