May sound sarcastic, not meant to be, but get your hits! "Fast" kills in IDPA if you dont score hits.
Number one thing - have FUN! The rest will take care of itself. I see too may people get all wigged out on match day. Truth is it's too late to worry anyway, the day is here! The preperation before the match is where your money is made and you have a solid plan. So, again, on match day relax, pay attention and enjoy!
