And yes, if you're left foot braking you're doing things horribly, horribly wrong. Doubly so for heel-toe. [...] Keep the fancy foot work for the track and dance floor, drive properly on the road.
OK, I've read some of the following discussion and you're all making interesting points. But in the world of "Everyone has an anecdote" I have an anecdote: My current car, a Mazda RX-8 was bought used, and the synchros in second and third gear were knackered. Second was essentially unsynchronized and third was a 50/50 proposition. The only way to drive with any fluidity was to heel-toe. And heel-toe saves wear and tear on the remaining synchros - drove that beastly gearbox for 6 years before finally replacing the box.
