Ted, the tape stripe at the top of the wheel is a good idea to ensure you are pointed straight ...

I always hold my left hand on the wheel between 7 - 8 oclock where my wrist is comfortable and my arm is resting on the roll cage door bar.

This makes sure i don't steer the car when the wheels come down. When i used to hold the top, i sometimes pulled off center when in the air...

Good luck,

Arnie
