When I used to play CPA (Canadian division of APA), and played a player lower than a 5, I would forfeit the break.  Caused a lot of confusion, but it ended up really raising my win/loss percentage against lower ranked players.  When I would break, I'd either make a ball with no shot at the next ball, or I wouldn't make a thing, and the table would be a roadmap.  Decided to let the other player do the dirty work.  It's not going to be a very clean rack when a 1 or 2 breaks, so their chances of picking off 2-3 balls is unlikely.
