GM,
I understand, I used to feel the same way. If you didn't have a strong opinion in the first place then it makes sense to middle at half. My records indicated that I was losing more than winning on those bets (as opposed to just letting original bet ride), so I swore off doing that as a general rule. I did have the PIT/CIN over for game and bet the 2nd half under, but only because it falls in Nolan's trends and they have been doing very well. GL to the under!
