I really did think most of the kicking styles in 08 were pretty much fine, maybe Jonny could have been perched a little lower - but thats being very picky!
I wouldn't mind just having a better default kicking style, or several defaults to choose from (i.e. a straight up run kick - Stephen Jones style, a normal run up - Morne Steyn, Cipriani, Giteau, Hernandez, Parra etc, and a longer straighter run up - Hook, Henson, Halfpenny, Francois Steyn) as there are quite a lot of kickers who have very similar styles.
Then the players who have completely unique styles such as Wilkinson, Carter, Quade Cooper etc can be motion captured.
It seems to me this would save a lot of time as tiny little things like one player tapping his foot and another breathing heavily doesn't really make that much difference when they both strike the ball in the same way. Then in edit mode (if there is one) we can adjust peoples styles as we see fit. In football games there are usually about 8 free kick styles which is plenty to cover the vast array of ways to kick a ball.
