No cringes here, just a dude getting to work...
I don't downshift through the rev limiter but I do ride WOT all the time and only use my clutch between 1->2.
FWIW I clutchless shift my "nice" bike about 50% of the time too. Unless you're horsesh!t at it it causes very minimal gearbox wear.
Dropped a gear... . . . . . . . . . . ...still here
