Using the above-described "double-clutch" ensures that all the internal

parts in the tranny are spinning at the same speed, thereby reducing

the wear and tear on the synchros.



While I profess to understand this, I've never felt the need to practice

it.  I've never had a tranny-related failure in 500,000 miles,

the highest of which was on American iron (120,000 miles).  I'm willing

to let the synchros have something to do.



Today's trannies are pretty robust.  YMMV and all that.
