Lets define some things first If you sidehop too close, thats fine for low stuff because your bars are going to be OVER the wall, even at compression. But as you go bigger, you'll be too close and your bars will hit/squash you fingers etc. So you need to be over half bar width away from the wall That said, usually the closer you are the better, but again, as the wall height goes up, you need to start further away, because you're travelling for longer which means you need to clear the wall for a longer time Its all trial and error really, and what feels comfortable to you. As Mr Vandart suggested pointing your front wheel at the wall is pretty helpful, not too much though, its still a sidehop
