If you can hit the berm, then you are good enough to compete. You can find a lot of comps on the Internet for your local area. Go to one for kicks, and have fun. You wont know how good you are until you try. I enjoy shoting comps because you never know what the end result is going to be. I have seen some top teams finish near last place at times, and vise versa.
I compete in order to learn, and have fun. The trophy is just icing on the cake
