Think all the contests offer something unique and are all fun to compete in. Having said that, I really liked the contest that the RIO sponsored this past year. A $300 sign-up or re-up was required to enter and every week they gave away $750! The contest was exceptionally well operated throughout the year. I like contests that the contest entrant is required to post-up some money. Think this keeps alot of contest whores and ghosts away from contests so both the book and the player are in a win-win situation.
