Reply to "Lane's Beck Super Coupe #3"

So let's see if I get this right:

1. Doing the heel-and-toe technique allows you to smoothly downshift and brake simultaneously, but doesn't necessarily provide any aid to the synchronizers unless maybe you allow for a little clutch drag will blipping the throttle.  I would suppose de-clutching slowly might support that.
2. A true double clutch technique can be mastered only by the superhuman, but does add the extra benefit of easing the load on the synchros.

I'm only partially kidding here as these are questions I've wondered about for a while.  If I take the car (or any manual car) to the track I need to master at least #1.
