So maybe synchros are just stronger than they used to be?
I think one of the arguments for double-clutching was to save the synchros, especially at higher rpms. And this was on road cars with full-synchro and all helical gears.
I do notice that downshifts and upshifts on my car almost require rev matching to go smoothly (upshifting, I pause in neutral a bit to let the revs drop). And I'm so used to double-clutching down that I never try rev matching any other way.
Old dog, new tricks.
