which book is more credible when it comes to MLB?...Pinnacle or Bookmaker?

[Da Manster!]

the reason I ask is because both are A+ and solid...both are very reputable and sharp....however, every so often you get two different lines on MLB totals and stays that way for a long time before any kind of line movement...for example, right now the total for Astros/Royals is 8 over at pinnacle

17.15	Houston AstrosD. Keuchel	-116	-1.5 +141	Over 8 -109	Under 8 -101
Kansas City RoyalsE. Volquez	+107	+1.5 -153

and over 8.5 (+EV) at bookmaker
