Tried new lap belt.
I tried out my second lap belt setup today. With broken layers above and below I didn't loop, but rolled a couple of times, and the second belt across my legs did add to my stability. I think the installation is plenty strong for my 183 lb weight. It might not be strong enough for heavier pilots and/or negative G maneuvers. The belt cinches up tight, and there was no deformation of the seat pan. John
