I find these kind of jumps just an obstacle really, 9 times out of 10 its faster to accelerate up to it brake roll it and then accelerate out of it then it is to actually get air off it, boring for spectators but faster and nicer on the car thats for sure, cant accelerate in the air and it also bottoms out hard most of the time if you land on flat ground hard on the gas. These jumps are ok for a worlds event etc. where it makes it tricky but for club racing its boring IMHO, doubles etc. are a lot more fun as they are fast and big air.
