There’s also two kinds of “hop round tight corners” techniques too. The “STOP – Apply front brake, weight on front, twist upper body then bounce the back up and round” which isn’t too difficult to do as you are stationary and keep the front brake locked on hard. Then there is the Pro “arrive at a rate of knots – shift weight forwards, feather front brake into a stoppie, rotate upper body to twist bike around whist you hover rear wheel about 2 feet in the air at 15mph”.
Needless to say, option 2 is rather more difficult, and much more prone to getting out of hand if the surface / terrain changes unexpectedly………
