Pit: Hello sirs.
Whip'll give you a run for your money on the track. She's good for friendly competition in the race, but get her anywhere else and she plays to win.
Pit's not the best lady to choose for decision making. She's capable, of course - but in the end, she's just gonna go along with what you say.
Stone's your go-to for actually having fun. As the least competitive, she often comes in third/last place. But don't be fooled - she'll give you a piece of her mind and then some.
