That sucks it happens though, there are some good videos on how to fall properly haha, tuck and roll!
Look at the tips section, there are some good videos/commentaries from people as well.
Uncomfy boots will ruin your day, bad bindings will ruin your day
Board is meh you wont notice a difference really from board to board
Just get a hybrid rocker or something then you'll be set for awhile. That carbon credit is a pretty good deal and will fit/last you awhile.
Take the time with boots, seriously. It takes me a few runs to get my boots dialed in but if they're too tight or too loose it's an absolute nightmare and i want to rip my feet off halfway.
