Do I take this sweetheart teaser on GB/CHI?

[09Gamecock]

Bears +13
Packers +7
Over 36.5 OR Under 56.5

Is this the best play to make tonight, getting -110 odds? I feel this game is going to be very close, but I don't know which side I want to be on! If I do it, what's the better bet -- over 36.5 or under 56.5?

Thanks for any input!
