Olympic is certainly one of the top books out there, but I wouldn't rank them #1. They get high grades for posting lines early and offering a wide selection of lines. Plus, they're one of the few books with a locked-in line feature -- i.e., a window of time to confirm a bet without the possibility of a line change -- a really nice feature. What keeps Olympic from the top IMO is that their vig is on the high side, particularly their props and futures (they did at least finally move to a 10 cent baseball line this season).
