Like I said in the other thread you should look into a Capita DOA. It has a cambered profile but not as much as the NAS and the contact points are flat/lifted so it isn't going to be as catchy.
This. Capita's Death Grip is kind of a poor man's magne traction (3 contact points instead of 7), but it does the job. I just passed up on a Custom Flying V and bought a Capita BSOD and the thing rails on ice. I ride at Stowe where we get a lot of ice/hard pack/variable conditions and I can tip that baby up on edge and ride it out while watching everyone around me go slipping by. So happy I did it.
