Code Bleu brides

If anyone has used the band Code Bleu or is going to use them for their wedding, I was wondering how many pieces you had. They are 8 pieces, but you can add the female ballad singer and a trumpet player. Did anyone add them and find them worth the additional $? Did anyone NOT add them and feel like they weren't missing anything? If you didn't add them, did you feel like something WAS missing? Please lend your opinions, I'm trying to decide whether or not to add the additional 2 pieces...TIA!
