Is there any way technically and legally to add a fifth strap to an ASW 15? No matter how tight I pull the lap belts they ride up when ridge flying allowing the shoulder straps to become loose. My head is pretty close to the canopy and a stiff jolt can lead to head banging if the harness becomes loose. I also know having the lap belts out of position can be very dangerous in the event of a crash and would love to alleviate these problems. mdfaddenatgmaildotcom
