Jake,
I think the NE spin rigs have lengthened the wires from the hull to the foil. This allows the pole to ride higher. This would also allow them to rake futher back. I guess they do this for the spin, doesn't seem like it would help upwind except in heavy air. I am new to the 6.0 so I am still learning the boat. See you at Spring Fever, hope we get some more 6.0s.
