As long as one of the blinds isn't a maniac, I call. You have great position and the pot is already laying you 8.5:2 which will most likely end up being 9.5-10.5:2. You are in a position to win a huge pot if you hit and can usually easily release on the flop it it doesn't hit you.

Also, not to use a book as too much of a crutch, but SSH does say to make the call even in a tight game. Just be sure you know how to play this hand post flop.
