I wouldn't let them totally pick. My parents know my tastes fairly well but I wouldn't let them arrange my marriage. I would want a say in it. They will have some say in my marriage since whoever I date, I want him to ask my parents first if he could marry me. I think A) it's common courtesy and B) it keeps the peace between you and your parents if you have a good relationship with them. And, my dad asked my mom's parents if he could marry my mom.
