Honestly? I was worried about BRs in HD also, but somehow it feels they are a lot less present in HD. Maybe because HD is mostly Pure tracks, and they don't lend themselves to BRs that much. Maybe they've also made the animation longer. I don't know what it is, but I can't think of a track that allows for more than 3 BRs in HD (and that's Chenghou, which happens to have 3 actual jumps, so BRs are justified, maybe Vineta if you're really quick), most tracks only allow for 1 or 2. I'm not exactly the master of BRs, though
