Tough call. Here is my advice. The call is really based on how you approach this, because the Black is a tough course. It will beat you up...
If you are going and then going to cherish the opportunity, not worrying about how you played, then that's great. If, on the other hand, you go and get disheartened about your play, then I say do not go.
Playing on a Championship course is a tough deal, because you really get a sense for what a place is like where the pros play. So answer the questions honestly and then you can decide.
