Quick poll (please let me know what you think)

Hey everyone, quick little unofficial poll here... Read below for more information. By attending this event, you are voting that you WOULD like the details to be announced ahead of time. By clicking "maybe" or "not" attending, you are voting that you would prefer to be surprised and that you would NOT like the details to be shared prior to the event.

So here's the question:

I plan on holding a friendly shooting competition with cash prizes for the top few shooters. The competition will include a pretty broad set of skills to level the field against shooters who are especially skilled in one area over others. The question is: Should I expose the tests prior so that people can practice up beforehand? Or would it be more fun to surprise everyone on the day of the contest? Let me know!

I'm not sure about the timeframe yet. Since I'm a real estate agent, I can't anticipate my next paydays and I want to give enough prize money to get excited about. That said, I'd expect the contest to be within the next few months or so.
