Leg stick problems will be caused by the head falling over a touch to the offside (take cook for example), bit like what golders was saying. It's important to try keep all your body in line - head, shoulders, hips, feet. I have just been videod and I have a slight dip over to the offside, at first we thought it was a big problem, although i take my guard on leg stump and stand quite upright. Been thinking about it, and had a proper look and the dip takes my head and eyes just over off stump which i feel isn't a bad thing? Looking for a bit of help too if possible
