What I would say Dave, is work on that front arm. It is so important to your whole action. It's easy to get overly focused on your bowling arm and not bother with that front arm, but it is as important as the bowling arm. What you don't want to do is scour the internet for examples of bowlers who have a similar front arm to you. That is just finding exceptions to try and disprove the rule and ignore issues in your own action. I've done it myself and done it for the front arm too. My front arm pushes out to the legside rather than at the target. I saw that Bishoo did that too and thought "well, it can't be that big of a problem". But that's the wrong way to think about it. Bishoo is a pro legspinner. I'm not. It may not effect him that much but that doesn't mean I should not fix it in my action. Same with you and Chandrasekhar. These people are exceptions to the rule regarding the front arm. Bottom line is, the arm should really pull down hard and at the target. Simple as that. If you are able to produce top, top quality bowling without doing that, fair enough. If you can't, then you must get that front arm sorted. I've been down to the nets today and focused on keeping that front arm higher for a fraction longer and pulling it down hard towards the taregt. It really is such a crucial aspect of bowling. There's a clip of Warne/Zampa and you can see that Zampa's front arm actually pulls to the offside a bit. Warne's is straight at the target. That front arm of Zampa allows him to rotate to front on really quick and late. At the very last split second, Zampa's chest is pointing to square leg whereas Warne's is facing legslip. Also, the batter can see the back of Zampa's hand (as if he is bowling a googly). The back of Warne's hand is facing towards him. But Zampa is able to get to front on and produce a decent amount of sidespin with a very, very late twist to front on. In the long run, he won't always do that and will lose consistency of accuracy because the action is too rushed. Warne's is, as you might expect, much more rhythmical and smooth. For me, that arm pushing out to the legside gets me too open chested and makes rotation less dynamic. There's no doubt about it. I have to get that front arm pulling down hard at the target and you do too Dave. I bet you find that your follow through is far better once you get that front arm working for you as it should do.
