That fall away to the left actually became a lot worse within 2 months of that footage. It certainly does hurt consistency. But it also tended to collapse when I bowled flat out. That's why I ended up finding myself having to do that work to get my chest/head going much more at the target and nearer to the line of the front foot. I did post this footage from a couple of months earlier: There isn't the same falling away to the left in that. I think working on the googly led to me dropping the left shoulder more and more to the point were my follow through was causing me to fall into the side netting at times. It was a gradual thing that happened over a few months. Regarding the run up. This is something I was looking at back in September. This was the change I came up with back then: I was using that longer run up purely because I came to the same conclusion as you, that having create all the energy at the crease was not ideal. I don't have to really sprint in like MacGill or Yashir Shah, but I do need to get a bit more energy into the run up. I worked out a 7 step approach a couple of months ago and focused on trying to keep that left shoulder upright. It was working but I was still not quite getting my momentum going forward enough. I was still falling to the left a little. I'm getting there. I started having issues with releasing the ball too early as well. I'm getting all that sorted now. As I said before, it's all about that centre of balance and getting the movement of the bowling shoulder coming up and through the line of the lead shoulder with, as you say, the follow through right at the target.
