I know that these programs are great. I also know that most winning players have/use them.

I'm just curious if there are any SNG winning players out there that don't use these programs or similar ones? If you don't use them, is it because you can beat the game without them? Or is it because you feel that you are a good player till the point that you don't need "extra help"?

Summary: For winning players, do you think that anyone can beat the game without such software, or is it absolutely necessary to use these programs to beat the game?

Elaborate.
