The double loop has always been my nemesis jump, even before I tore my ACL. I tried working on it early March 2012 but it just hurt. The double loop is a jump where you take off on your right backward outside edge and land on your right backward outside edge so there's a good bit of torque on the knee.
I started working on it again a few weeks ago and today I finally had success. It only took 2 years 9 months and 21 days to land after surgery, but I finally did it!
Also, please note that my butt really isn't that big--I'm wearing crash pads.
