I ask this because I have a lot of respect for your batting advice. My dd use to do the squat,bend at the knees and waist set up. She herself found it to be really uncomfortable, she now looks like Pujols in her set up, I would think that would be worse, but she likes how it feels and she really has been destroying the ball in the cage off of live pitching. My question is what do you find the advantage is for doing a set up like Casey's? Also what would you find to be a disadvantage in my dd using a set up like Pujols?
