Niners Seahawks Thursday Night Situation

Here's the deal: I am stopping at a casino Thursday night to cash a large ticket and want to roll it into this game.  Looking for something that pays even money.  I am a sports gambler but don't do much on the NFL as I am in a bunch of pools and fantasy football so plenty to worry about each week.  I follow the NFL very closely just don't bet the games, until this Thursday.  My initial lean is 49ers and/or Under.  BUT we all know the NFL is crazy and especially on Thursday nights.  These are 2 teams going in opposite directions so likely the reverse wouldn't surprise most.

Here is what I have selected so far as possibilities.  Please weigh in on your opinion of the 2 or other options (that pay even money)

1) alternate total under 42.5 

2) parlay: niners moneyline and alternate total u 53.5 

We need to wait till mista posts I don't bet until he does

 ?

why not sea + o43.5 

@Paal

 My initial leans are sf and under but I am open to all ideas if they make sense.

Don’t overthink this Do you not see the writing on the wall. The spread is only 3 1/2 because well yes Devos hurt this is the kids second start yes the Niners have not won in Seattle in forever Seattle always play them  tough on and on and on but Seattle  Gio they are going south and the Niners are going north the Niners defense is ferocious they will get  after Gio he will make huge mistakes and this young second coming of Joe Montana Brock Purdy will be the talk of the NFL after Thursday night when the Niners demolish Seattle

@dustmiester

Based on everything I have capped and read here this week, my mid 4 figure play will be on the under.  Not sure which # I will choose, depends on what options the book offers.  Thanks for the input and info.

@pj719

 Only thing to worry about the under is turnovers by both qbs. Gl to your bet. I will most likely bet under as well but still mulling it.

@Martylee

 Thank you.  Turnovers are the ultimate "uncapable" variable.  The only reason the Eagles aren't still undefeated.  I see 34-41 points in the game. 

@pj719

  Ever bet a player prop.Bet Chris McCaffrey over his receiving yards 39 yards. Missed last week as they took him out and rested him in a blowout.

@SelectivePlayer

 I'm thinking about that(saw your post) just curious if the book will have a limit on that type of play.  Side (or total) likely only large play option

@pj719

  Depends what kind of limit you have with your office. You can max out on it.I dont know what you bet, but i only bet props and have a gooid limit withjmy office.Have put in up  to some huge plays.Good Luck my friend.
