depends on How big the book is,,, a BIG book can make HUGE dollars just letting the LINE fluctuate,,, and take their cash from the VIG, teasers,,,and PARLAYS,,
A smaller Book will probably jump their lines accordingly trying to keep on the SHARP SIDE of the Numbers,,,,
The Joke ,,, is that I know of some books that will ABSORB a MOVE because a TOP handicapper is on the opposite side of the steam,,,, by doing this they can BAIT in more money,,, on the POTENTIALLY WRONG side by keeping the line "LOOKING WEAK",,,,
