As a wakeboarder you condition yourself not to let go of the handle early because nothing sucks more than riding away without the handle because you didn't believe you would land with your board under you. I remember one weekend my boat driver bitching at me for letting go; "loose the rope, loose the comp".
Well, one thing does suck worse. The pain in your shoulder when you didn't let go at the cable park while trying to learn load/release tricks in the flats. I dug in so hard that my board almost got ripped off my feet. I didn't commit to the flick and all the line tension wemt into my shoulder... doh.
