Probably a topic more appropiate for the Think Tank but I figure there will be more opinions here.
Why are people still buying the hook?
I've been guilty of it in the past myself. Now I don't get involved with the hook any more. I figure in the long run I spend more on insurance of something that rarely enough comes into play than I win by purchasing it.
If a game is so close that the hook is a serious concern then it's too close of a game for me to make a play on. I'm not saying it doesn't bite sometimes but generally I either win or lose by enough of a margin that I rarely ever see the hook play a role in the outcome.
