Cut more than 4 seconds from my previous best run of 45.16 without touching the far right half moon wall. This is the best time I could muster employing the quick ninja bounce back onto the yellow truck. Pretty sure a 39.xx or maybe even a high 38.xx is possible, but the recovery from the slow speed moving back over the truck crushes the strength of an otherwise good play.
Here is a head to head of my best 3 runs using the bounce.
