Mr. Jones,
I'm not sure if we are considered a upper-tier book, but we post lines Sunday night for the following Saturday games and intentionally try to hang different numbers. The term "opionated lines" is an interesting one. Just becuz a line is different why does it have to be labeled "opionated"? The answer is the internet. Before everyone could see everyone else's lines on the internet, everyone had different lines and none were labeled opionated. My handicappers maybe see some games different than the handicappers at Cris or Oly. I don't it makes my lines opionated, just different. Anyway, we were pleasantly surprised by the amount of action the first week, but it has dropped steadily each week.
Hope this helps.
Lenny
