You also need to ask them how they play their SNG's i.e. how many tables, in sets or continuous, whether or not they take a break when bad beaten?

And also, I found out that alot of people wont even watch after they make a hard decision, so they wont be results-oriented.

Maybe have them decipher a gigabet post? Not that there's a right answer, but it will DEFINITELY divulge their thinking pattern.
