using only a rooster booster would not get you that much up angle to throw that much roost.
theres a lot of modifications that need to be done to achieve that level.
the guy's boat in the video kinda handles like crap. someone post up a video of tard's boat at speed with full roost. yeah, it doesnt have a rooster booster, but it has the same amount of up angle as that dude, but it rides MUCH better.
