Without giving any details---I can only say this--- Heritagesports is the number 1 Book in the business. Their customer service and all the reps are the consummate professionals. I would recommend this Book to anyone looking for the Premier place to wager---Kudos to the folks at Heritagesports!! I have played at several different sites over the years and have found some really good books out there--But Heritage is in a league of its own!!
