Some variance in series prices between Pinny and 5Dimes, but for those who have accounts at both I would suggest shopping if you want to lay anything on any team winning it all (even to hedge later), as the lines differ pretty hugely with some teams.
For example:
Stars (Pinny) +1159
Stars (5Dimes) +700
Sharks (P) +2951
Sharks (5) +1600
Rangers (P) +2445
Rangers (5) +1700
There are actually some lines where 5Dimes has a better line, but certainly not in the case of these few.
