Mike,
Drop by the TA sometime this week,I think I see something in your films that may help.
Muzzy makes a good point about switching from the spit but I think you still need some work on keeping the enemy in view and using the lift vector to do that.Once you get your head wrapped around that then I would suggest you change to another plane.
I would suggest a plane that you must use flaps in,as the spits dont really teach you how to use them.
