Help a newbie to online sports betting (Miss St and the points)

[Murdz]

After years of betting with a local bookie and banging my head against a wall, I am experimenting with betting offshore this season. The season hasn't even started and I face a conundrum.

I like Miss St with the points tonight. Pinnacle has it at +7 and putting up 105 to win 100. BoDog as is their custom is shading the favorite and has Miss St. at 7.5 but you have to lay 115.

I never had these dillemas when I bet with Sal the Chin. So my question is this: Is $10 in juice worth a half point? My gut tells me no. Take the nickel odds at Pinnacle but if someone has math or logic to back this up, I would appreciate it.
