Static vs. BGP routing for an ISP

Ok.second question today. I am on a roll.

I cannot announce less than a 24 bit subnet to BGP. So my ISP used static routes to me.
Do I still have to use BGP and receive the entire BGP routing table to enable outbound internet traffic or can I just put a default static route in my egress router that points back to my ISP?

    Yep. That's all you need:
      ip route <ip address of ISP>

    ! done !

    More specifically, you can choose what -- IF ANY -- routes you receive from BGP.  Unless you are trying to pick an outbound gateway based on destination (a rare situation), a default route is all you need, and it can be static or learned as you prefer.
