I tend to stand with the tiller between my legs, take two wraps on the winch with the jib sheet (makes it easier to sheet-in) and release the holding sheet with an upward pull as i jib through.
I use three bungies (i'm cheap) instead of a tller-tamer as cam mentioned. Wrap one around tiller and connect the others to each side. The one around the tiller has enough grip to hold but is easilly ajusted with a twist.
Then sheet in tight and relax.
