David,
Have you ever driven a car with a non-synchro gearbox? I suspect not -
since that procedure described by Skye as "single-clutching" would be
absolutely useless when downshifting into a non-synchro gear. (Think of
a non-synchro gearbox as one with REALLY worn synchro cones...) Go with
Lawrie on this issue - he's right as usual.
By the way, for those who haven't used a non-synchro gearbox, and I mean
all the gears, do you know what the proper clutch/throttle procedure is
for upshifting?
