This is just my opinion but I think if you are planning to have multiple books (which is the best policy) then the best idea is to have some of the bigger books like CRIS and some of the smaller limit books like VIP. The reason I say that is that CRIS, Olympic and Pinnacle are nice because they tend to get lines up very early and have higher limits while you probably tend to find softer lines as the day goes on at a smaller limit book like VIP, Game Day or Sirbet. Again, this is just my opinion. I know everyone has their own comfort zone on which type of books they like.
