Seems to me the spoke of the wheel would interfere with a 9-3 position. Someone else recommended 8-4. That accommodates the spokes, but I think it would be uncomfortable. Of course, not as uncomfortable as getting your hand blown off.
The spokes of the wheel are usually set up to not only allow but encourage a 9 and 3 hand position. Professional rally and race drivers never used 10 and 2 as it is less conducive to control in the first place.
