Different lacing patterns do different things in response to dynamic
loading of the wheel.
Ron Ruff's radial NDS side suggestion would give you the stiffest wheel
because the NDS spokes heads in give the highest possible spoke sup****t
angle along with the shortest possible spoke length. My suggestion of
heads out gives a more tension balanced approach making the NDS spokes
take up more of the load. Either way, if any torque is transmitted to
the NDS side spokes, they will increase in tension due to the torque.
If you choose 2X NDS any torque transmitted to NDS will be shared with
the DS side spokes.
2x NDS is a small compromise in stiffness and load sharing due to the
spoke sup****t angles, while assisting in the small amount of torque that
is handled on NDS. I would be comfortable building your wheels radial
front and 2X both sides rear.
