Barry,
Other little tips for Marissa:
To regulate your slower speeds, also good for 'U' turns etc, it's best to keep the rev's up (within reason) and 'ride' the rear brake. This is far easier that feathering the clutch.
When executing 'U' turns and the like, look where you want to end up, not where you're going. In other words, if you're doing a 'U' turn to the right, look over your right shoulder to a point on the road where you intend to end up, keep the rev's up, ride the rear brake, do the 'U' turn, release the brake and all should be well.
We get this taught to us on the Priority Pursuit Course. It's a lot easier, quicker and you can do a tighter turn.
Not trying to teach anyone to suck eggs but it's amazing how many riders don't know how to do this.
Good luck and well done Marissa.
