and you should
I also vote for getting the feel of the sport then next year build a set up. It doesn't ride the same, more chance of injuries.
As we would more than likely see a very near future post " I F'd myself up on my new backyard jib set-up" video to follow.
Take your time and enjoy the sport you'll have a blast.
