The reason for not leaving your hand on the shifter is the chance that you would preload the synchronize rings and can cause premature failure. Just that simple. I once heard of a racecar driver that would preload a emco sequential trans and after a race all the blocker rings would be blue from from heat. So whatever is comfortable for you but it would be a good idea to brake the habit.
If you're putting pressure on the knob one way or the other then that would be rather silly. It would also be a good way to pull the car out of gear if you happen to let off the gas for something.
One of those is a poor driving habit, the other is a decision to ignore a bureaucratically developed rule for the lowest common denominator driver. Yes, I lapse into poor habits also; but, I try to correct myself. Not being prepared results in thousands of vehicle accidents a day, IMHO.
Fortunately a good driver can still be prepared while only having one hand on the wheel. As well as having just as much steering wheel rotation available as with 2 hands. Regardless, I'm not here to discuss driving technique. I haven't managed to go 17 years of avoiding the average licensed idiot by exercising poor driving habits and not paying attention.
The knob feels great!! It showed up today along with my package from VPA containing the blue stitched shifter and e-brake boots. Now all I have left to do for this summer is install the back up camera, amplifier, and Subwoofer box which is scheduled to show up in the mail tomorrow.
