I assume you are in NC? Not sure what books are legal there if any. I have used all the big name legal books and MGM is by far and away the best. They give the best promotions, etc. Once you reach Platinum level, if you are a decent size player it won't take too long to hit Platinum. Not only will you get great odds boost promos, free plays, pretty much daily, you will get assigned a host who will offer you tickets to the best games, concerts, etc. They treat their sport betting app just like they do a Vegas Player. I'm far from a HUGE player and I've been in every Luxury Box in town, for every team, concerts, etc. More importantly, the promos just keep coming, 10-25% guaranteed play, if you are a parlay guy I get 10-15 Parlay odds boost promos a week, the list goes on. If you are looking to stick with one book and get all the "perks" for doing so, no one is even close to MGM. Cheers
