For someone who used to get LBW'ed (a lot) to pitches landing between middle and leg stump, becoming more front-on helped a lot - somewhat Gary Palmer style batting where toes point down to opposite stumps. If you tend to straighten up early, like I do, then off-side shot options becomes limited. Unless, there is a lot of pace or ball is hard and new, it is very hard for me to cover drive a ball to the boundary.
Off-side is over-rated as a scoring option. So many batsmen get caught out on the off-side trying to play "pretty" cover drives when there are two fielders on the off or leg side. No wonder KP prefered on to the off side.
