First off your friends sound like a bunch of idiots that want to make you feel bad. E-man Anderson rides that board, you can definitely ride it. It is a jib specific board but that doesn't mean you can't ride it on jumps, it just won't be very stable for sending it off big jumps. I don't think you want an all mountain board because they won't perform as well in the park. If I was you either keep the Jib Stick, or get a Capita Horroscope, or Ride DH. They are two park boards which will still allow you to ride the mountain.
