Continuing the discussion regarding "the knuckle" which was/is one the tenants of Greenough board design...
I came across this mid-70's shot of Jeff Hakman dropping in at Pipeline. The "stock" rocker set up from that era -- apex well forward, with a semi-straight bottom curve running through the tail -- accomplished two things at once. It was flat enough, nose to tail, to generate a lot of lift and drive, while at the same time had enough of a "bump" in the front 1/4 to handle serious adversity...as is clearly visible here.
Today's boards have done away with the forward apex/knuckle, and settled for an overly generous curve running nose to tail that doesn't come close to maximizing the rocker's potential.
Just my 2 cents...

So... How do I shape the knuckle in? It seems to me to be moving the wide point forward and getting the rail line to transition from high to lower. Is this right?

The apex of the rocker and the main break of the outline curve have to be placed in generally the same spot on the board...which should be ahead of center.
The shots of Jeff Hakman demonstrate the knuckle on a board with low rails nose-to-tail. But transitioning the rail line from high to low in that same area of the board can also achieve the same effect.
