If you want to make a Belgian wit the you need the Belgian wit yeast. To my knowledge there is no dry Belgian wit yeast for sale. That strain is only available as a liquid yeast from white labs or wyeast. So yeah if that's the style of beer you want to make you need to use the right yeast. If you used a different strain you'd have a different beer.
Remember to make a starter.
