Here's a wichard setup like most racers use, this was my setup prior to the megatron. I do need to add that I used a Peter Lynn spreader bar on my harness with a D-ring attachment point.
It has its advantages, short length, free rotation etc, but I preferred the ease of release on the megatron . The wichard release required some small changes as you can see here, I used a bit of dyneema , covered with a piece of plastic tubing and made a new pull cord with a stopper ball on the end. This meant that I could grab it in an emergency but you have to ensure that the cord will never wrap itself around the wichard and prevent you releasing the kite.
I used my megatron setup at the champs in cherruiex a few years back and it flew through scrutineering , in fact they really liked it!!!
