Personally I don't like to see any flips in the future of trials. All these huge CLS drop gap stuff pisses me off already. I prefer a more technical riding, rather than insane, powerful drop gaps, flips or any kind of moves where it's mainly about raw power and crazyness. But that's just my personal opinion. Beside that, flips and trials doesn't really fit together. When done by bmx riders, it's ok as their sport is more fluently and involves more riding, rather than balancing and static moves. Flips on a trials bike would look pretty dumb then...
