The diamonds appear to be setup just like the infusion mast...which is a really slick system. There is a foam plug above the diamond wire hole in the bottom of the mast to seal the rest of the mast. Diamond wire tension is adjusted with a big nut at the bottom of the mast...really easy, really slick. I really like having the rotation limiter down low too.

These developments are all coming out of the F18 class and it will be nice to have them on a 20.
