that's what truly keeps it interesting for me
I have three sites I watch for my lines and one is an overseas site in australia that's a UK site clone
they're about 7 hours ahead and a sophisticated clientale so I get spread moves earlier than the US sites and they are reliable
that is the UK/aussie site doesn't cheat the odds like many US sites,bodog in particular
for the superbowl I saw 6.5 in a couple of places and I doubt it's going to either 5.5 or 7.5 so I put the 6.5 out there early to generate speculation and get the "talk" started early
as you know even numbers suck because noone wins if the final falls on the even number
e.g. if Indy is favored by 7 and wins 28-21,noone wins
still though I won't move a line off an even number unless I see it posted at reputable site
