It said in another topic that if you side hop to the same side as your forward foot. Doing small sidehops isn't to bad. But when it comes to the bigger sidehops it will make it harder to tuc. After i read this i watched a few videos and it down make sense. The forward foot, well the leg goes right up to your chest. So if going to that side it seems it would be harder to tuc and get onto the wall.
