I use the standard Finishline component that I smoothed the welds on and had triple-chrome plated to match the hoop. I use the offset mounts to center the straps to my body. I'm also 6'3" so the mounting points are neither too far above or below my shoulder height. Too low and you can cause injury to your spine. Too high and it negates the safety. The original mounting point (to the frame) can still be seen just above the seat. I also use a crotch strap that is mounted to the floor bracing, so it's a true 5-point system.
