Organic or high wall yoyos are great for rejections so that might help you get it to happen. For rejections I just try to remember to keep my string somewhat taut, if your hands are loose and the string is loose its gonna be nearly impossible for the yoyo to reject. It looks like he swings it forward as well so try to be tight when you do that. Lmk if that helps at all
I think that’s where I’m most lost. I can’t tell if he pops it up and twists to get a rejection. Or forward with a twist. Just trying to do it right but I see it two different ways from the video
