Match wedge bounce to bunker depth
For bunker play the speaker recommends matching a wedge's bounce to the type of bunker: in shallow bunkers use a lower-bounce wedge (around 10 degrees or lower), and in deep bunkers with a lot of sand use a higher-bounce wedge (around 14 degrees) so the club doesn't dig and get stuck in the sand. He frames it as a rule of thumb for choosing which wedge to hit from the bunker.
