Man, the wrist lock was my favorite thing. I was wristlocked ONE time and then I went wristlock happy and caught it a lot of times. It got me out of bad positions when I was in someone’s triangle or mounted. Nothing fancy, just the novice grab-the-arm -and-push-the-wrist-down style wristlock....Then one day I wristlocked this guy in his 40’s and he yelled out “Agghhhhhhh” and we stopped and he spent some time bending his wrist back and forth. I felt like such a jerk after seeing his pain I quit going for them altogether.
