Playing vs. 'maniacs' - limit

[MNpoker]

If you don't mind me asking,

What makes it so you win live but not online?
- Perhaps the live players are worse (OK let's assume that). So online drop down to $3/6 then. Can you beat that game?
(Playing 4 $3/6 games on line will give you about the same win rate per hour as 30/60 live if your BB / hand is the same.)

there is no way anyone can convince me that the 3/6 game online is tougher than the 30/60 at Canterbury (Fall Classic or not).

Are there other reasons?
Just curious.
