How do I tell my dad I want to switch churches?

I attend a Presbyterian church, and my dad is the pastor there. Recently, the church has been moving in a direction I do not like. They have been encouraging casual dress more and the music is becoming more contemporary. They also said that they want to get rid of the hymnals and project the words on a screen up at the front once they get enough money. I have always preferred a more traditional church service and there is a Presbyterian church in the next town over with a service that I like better. My friend who lives in the same town as me goes there, and they said that their family will pick me up on their way to church on Sunday mornings if I wanted them too. By the way, I'm only 16.
