Wait side spin? I mean they also have backspin right? Shouldn’t that help with the grip, even though it’s a synthetic pitch? Also how do you differentiate between the orthodox backspin vs big leg break?Can you feel when the hand is rotated fully that it’s a orthodox backspin and not big leg break? I hope what I am saying makes sense
Edit: I feel like once you turn your hand around from normal delivery to impart backspin, it’s quite hard to grasp whether you have turned too much (orthodox backspin) vs not (big leg break). Or maybe it’s just me and it will come with practice?
So what I would imagine the big leg break is, is a legbreak bowed with almost entirely side spin. The idea being that if it grips it will turn a lot.
Putting backspin on it doesn’t make a whole lot of sense because that will make it less likely to grip and just slide on. With the speed that spinners bowl at the backspin does nothing other than make the ball skid on, like with the flipper/slider.
You want to get the seam at as much of a 90 degree angle as possible.
I would wait to consult Dave though because my idea of big leg break might be different to what he’s referring to.
