I am a novice user and just got a used Tornado T2000. I have noticed that the score pegs have 5 blonde pegs on one side and 5 black pegs on the other side. I have seen pictures online of a mix of 4 blonde / 1 black on one side and 4 black / 1 blonde on the other side. What is the proper setup? What is purpose of two colors on one side? Also, Do you pull peg towards or push away when goal is scored?
