Hi guys/gals;

I've often wondered this too - especially as both my '66 1600
and '69 2000 have crummy 2nd gear synchro's.  As I understand
and practice the fine art of double clutching, it goes something
like:

1) first gear (faster, faster)
2) pull the trans into neutral (this would be the first of
    the two clutchings if one were so inclined, but IMHO, you
    don't really need to clutch the first time, just ease up on
    the ol' gas-a-rooskie)
3) rev the engine up to approximate the revs that the engine
will
    be turning once you get into second (doing this with the
trans
    in neutral and the clutch engaged speeds up the input shaft
    of the trans, ergo less grindage!)
4) press the clutch and slip the shifter into second

With practice, you may find that you don't even need to clutch
the second time - when you can do that, you're *really* matching
the revs!  'Course, the penalty for poor technique will be
grinding gears, so try this at your own risk:-)

So, to those in-tha-know, is that double clutching, or is that
just psycho-pshifting?
