Wow that sounds like an intense ordeal.
Words of advice though.. If you plan on getting back on a bike, take the MSF course. It will teach you alot of techniques you could have used to try and avoid the crash.
From what you have described you completely messed up on the braking.
Rear braking is a great way to high-side the bike. Not to mention 95% of your braking power comes from the front.. As you found out once you grabbed a huge amount of it.
Get well Travis. Hope you get back on next season.
