Beautiful bow, and an interesting design. Has me thinking... you say there is a clap, so I wonder if the limbs are moving faster than the slat on the belly at release? I would think ideally the slat should be trying to recover faster than the limbs to help push them through the shot. Video would help to see the timing of that. Not sure what you could do to affect it though. Really cool idea though and the execution is amazing, really nice bow.
