I have done a fair bit of analysis of my videos and watched a lot of Warne's video to see where my action differs. http://www.youtube.com/user/chippyben1?feature=mhum#p/f/0/AyHX7GsrMlo
As you all know I have a very high arm action that sometimes goes past the vertical. After a lot of watching the videos and standing in front of the mirror just trying various things I have noticed the main difference. I have been trying not to lean so far to the right in the picture above. To correct this I had been trying to get my weight on the top half of my body further to the right, leaning to the right of the red line. But still I ended up leaning way to the right as my delivery continued.
What I have discovered is whilst getting into a good position early, as I continue,
a) My head leans way to the right (in the picture)
b) The weight shift from the head opens up the left shoulder,
c) a and b in turn cause the top half of my body to lean way to the right of the picture,
d) This in turn brings the arm up into a very high position and
e) My front foot starts out pointing towards fine leg but because of my lean the front foot opens up and ends up pointing to the slips.
When you watch Warne his body stays a lot more vertical than mine.
I have just had a session at the nets trying to keep my head and upper body far more upright and it seems to be working nicely after a while. It felt quite strange as all all changes do but it started to feel a lot more 'correct' after a few overs. I really need to video it to see whether I am actually doing what I think I am.
I'm not really aiming to get a round arm and I have been bowling quite well with the big lean. I still like the high action I just want to eliminate the slightly past vertical arm that tends to cause the ball to go down leg side.
I also noticed I was getting more turn as my arm got slightly lower but on the downside the seam position on the deliveries was terrible and I have no idea why that changed.
