Not sure where to start with this potential train wreck.
Never hedge using the same SB (sports book) no matter how smart you think you are.
By using 2 or more different SB's you have three possible outcomes when hedging. If you don't understand this basic principle, then you are not ready.
Win one, lose one, tie both - Line the same
Win one, tie one - Line different by .5 or more
Win both - Line different by 1 or more
Place many bets over time and not one and done. There are a ton of SB's out there. You will keep getting offers from them.
