It all depends on who the judges are and who you are competing against.
Different parts of the country have different preferences.
Expecting to win a bbq contest with judges and other competitors from the same part of the country that you are not from is a difficult task.
So let's assume this is not a REAL competition, but more of a friendly backyard faceoff.
Assuming I have a few weeks to prepare and train, and am a novice at competitions and pulled pork bbq, I would spend time on the Internet to get trained about the topic, especially in my part of the country. Then I would cook at go through the process at a minimum of 10 times to prepare.
If the competitors are from the area and similarly inexperienced, you will toast them.
Otherwise, spend a couple afternoon chilling out while you try 2 or 3. Then pick one and hope you can duplicate it.
No matter the challenge or intensity, it does not matter. You have fun and get to taste (hopefully) great food.
